I have been using Sensate™ Fish Accelerant 95ml - Natural and have found it so good I'm about to order some more. The fish seem to love it and I catch far more than my friend who hasn't bought any yet. Wonderful stuff.
Squeez-Ready™ is also very good.
Recently took a bag of squeeze ready method mix to my local fishery, matched with 2-1 for a hook bait and I can see what all the hype is about. No faff no mess quick and easy to use, and to top it off the fish love it.
