Swim Stim F1 Sweet Pro Expanders 4mm 300g
The F1 Masterclass.
When you are targeting F1s, skimmers, and "match-sized" carp, the F1 Sweet Pro Expanders are your most valuable asset. This 4mm version is perfectly sized for the pole and provides that irresistible creamy-sweet aroma that has become the benchmark for commercial success. Built with Pro Expander technology, these pellets give you the softest hookbait possible without the frustration of it falling off.
Exclusive F1 Sweet Recipe: Infused with a unique blend of sweet stimulants and high-quality proteins that F1s find impossible to resist, especially in colder conditions or when the fishing is scratchy.
Superior Hook Retention: These aren't your average "mushy" expanders. The "Pro" structure ensures that once pumped or soaked, the pellet remains resilient and "rubbery," allowing you to ship out with total confidence.
Fast-Acting Attraction: The open texture of the expander allows the sweet attractants to leak out the moment the bait hits the water, creating a localized scent trail that guides fish directly to your hook.
Easy Preparation: Whether you prefer a pellet pump for an instant sinking bait or the "overnight soak" method, these pellets absorb water evenly, resulting in a perfectly uniform batch every time.
The Bottom Line: If you're fishing a commercial match, F1 Sweet is the industry standard. This 4mm Pro Expander gives you the perfect combination of a soft, "natural" take and the durability required for high-speed match fishing.
