Has anyone tried any of the mainline high-viz double strength pop-ups?

SORRY MATE CANT SAY I HAVE,BUT A BAG OF RICHWORTH POP UP MIX[THEY COME IN MOST FLURO COLOURS] 30ml of flavor/egg and you have a pop up that will work anywhere.old english toffee/pineapple are two good flavors but at the end its down to personal choice and most of all confidence.

cheers

would agree withother poster but not so high on the flavour m8 may be try that see what works level wise 4 youself m8 it can pay to be different. my m8 has made 8mil pineapple and 1mil of buteric acid hes catching everwhere ,hes tried that on 1 rod,thats allways the rod thats gone, like i said pays to be different,b lucky m8 what ever you try ,steve

Still perfer the corkballers myself with good measure of glm and albumin in the one egg mix.12mm corkers and i can get down to near 16mm hard bait,trimming off the cork if i want em smaller and they stay up alright.
Find the Richsworth mix too bouyant on it`s own for my liking and needs cutting with a base mix.Good for smaller baits.
The Solar microwave stuff sank after a while and would swell like a sponge.
Never got on with the Nutrabaits pan mix either,just couldn`t stop the pop-ups burning or having flat sides to them,came out looking like a burn`t pencil eraser head
Going to have to give this powdered/granulated cork method a go sometimes for a laugh.

used the nutrabaits one very very easy to follow cant go wrong really

Got to admit, the Richworth is the best ive used. I use 2 parts popup mix 1 part birdfood (by quantity not weight)
I can fish a 16mm botton bait and popup together and the baits sink slowly under the weight of the hook. Ideal for fishing over weed.
