Product Details and Uses

Mainline Match Stick Mix Liquid ISO Sweet (500ml) – The Year-Round Attraction Booster | Gerry’s Fishing

If you’re looking to add a “nuclear” level of attraction to your bags and sticks without melting your PVA, you’ve found it. At Gerry’s Fishing, we’ve seen the Mainline Stick Mix Liquids become a permanent fixture in the bags of the UK’s top carp and specimen anglers. The ISO Sweet variant is the perfect addition to this range, offering that mouth-watering hybrid of ISO Fish proteins and a creamy, palatable sweet kick.

What sets this liquid apart is its sheer versatility. It’s thick enough to cling to your bait, yet 100% water-soluble, meaning it won’t just sit “dead” on the bottom—it starts working the second it hits the water, regardless of the temperature.


Technical Specifications

The ISO Sweet Stick Mix Liquid is engineered to be a “plug-and-play” attractor that enhances any bait presentation.

Feature Detailed Specification
Volume 500ml Easy-Pour Bottle
Flavor Profile ISO Sweet (Fishmeal Core + Creamy Sweet Palatants)
PVA Status 100% PVA Friendly (Safe for Mesh, Bags, and Tape)
Solubility Fully Water Soluble (Effective in all temperatures)
Target Species Carp, Tench, Bream, and Roach
Application Internal mix additive or external bait glaze
Overdose Risk Zero (Natural, food-based stimulators)

The “Stick Mix” Advantage: Why It Works

1. Total PVA Safety

There is nothing more frustrating than a liquid melting your mesh before you’ve even cast out. This liquid is formulated to be completely PVA friendly. You can mix it directly into your stick mixes, squirt it into solid bags, or even dip your PVA mesh bags into the bottle for an extra “kick” of attraction.

2. All-Season Performance

Unlike many oil-based attractors that congeal and “lock up” when the water temperature drops, the ISO Sweet Stick Mix Liquid is water-soluble. Whether you are fishing a frozen-over pit in January or a baking-hot reservoir in July, the liquid will disperse evenly, carrying free-form aminos and sweet stimulants through the water column.

3. The ISO Sweet “Hybrid” Scent

By utilizing the dedicated ISO Fish base and enhancing it with sweet palatants, Mainline has created a signal that is both a food trigger (fishmeal) and a curiosity trigger (sweet). It is highly effective for “big weight” Bream and Tench as well as specimen Carp.


Where to Use & Application Examples

  • PVA Stick Mixes: The primary use! Add it to your dry stick mix until it reaches a “damp sand” consistency. It ensures the stick stays compressed and explodes with flavor on the bottom.

  • Boilie Glugging: Pour a generous amount over 1kg of ISO Sweet boilies. The liquid will soak into the skin, softening the bait and creating a “halo” of attraction that leaks out over several hours.

  • Solid Bag “Boost”: Before tying off a solid PVA bag, inject or squirt a 5ml dose of liquid inside. When the bag melts, it creates a concentrated “puddle” of attraction right around your hookbait.

  • Groundbait & Method Mixes: Use it to replace a portion of your mixing water. It adds a “sticky” element that helps the groundbait stay on a Method feeder during the cast but break down quickly on the bottom.


Gerry’s “Session Winner” Pro Tips

  • The “Double Glaze”: For maximum impact, glaze your boilies 24 hours before your session. Just before you cast out, give them a second “flash” coating. The first layer is absorbed for long-term leakage, while the second provides an instant “strike” signal.

  • The “Stick Mix” Slop: If you are fishing for Bream or Tench on the pole, mix this liquid with some ISO Sweet Groundbait to create a “slop.” This creates a massive, sweet-fishy cloud in the water that pulls fish in from the mid-layers down to your baited spot.

  • Winter Attraction: In cold water, fish have a diminished sense of smell. Using a highly soluble liquid like this ensures that even the smallest “sip” of water by a fish carries the ISO Sweet signal to its receptors.

  • Pellet Prep: Use it to “dampen” your 2mm micro pellets for the Method feeder. It adds a sweet scent that sets your feeder apart from everyone else using plain water.


Frequently Asked Questions

Can I “over-glug” my baits?

No! Because the Mainline Stick Mix Liquid is made from natural, food-grade attractors and stimulators, it is impossible to overdose. In fact, the more you use, the stronger the signal you are sending out into the lake.

How is this different from “Smart Liquid”?

While both are highly attractive, Stick Mix Liquids are generally denser and designed to be integrated into mixes or used as a “soak.” Smart Liquids have a more aggressive “climbing” vertical dispersion. For sticks and bags, the Stick Mix Liquid is the traditional “banker” choice.

Does it need to be kept in the fridge?

No. It is shelf-stable and can be kept in your carryall or tackle shed. Just keep it out of direct sunlight to prevent the liquid from thinning out too much in the heat.

Will it work for silverfish like Roach?

Surprisingly, yes! While it’s a “Carp” product, the sweet, creamy nature of ISO Sweet is a massive draw for big Roach and Hybrids, especially when used in a fine groundbait mix.
