Its my opinion Steve based on experiences and observations, albeit limited. Obviously im not saying its right, but i have far more confidence in my approach by fishing pop ups (if the fishing situation warrants it) without the use of an added PVA stick, and my results prove that.
The reason being, a stick is supposed to add attraction to a hookbait. The contents of the stick mix will be hard on the deck of the lake, yet the pop should be wafting above it. To me thats unnatural and defeats the object of using the stick in the first place. Why attract the fish to the bottom of the lake to feed, then put it on guard by using a bait off it? To me it doesnt add up. Like i said, im confident in my approach that i can get more takes when using pop ups without the stick, than when using one.
On the flipside, im also unsure of the presentation side of things. I dont want to risk my critically balanced pop up being snarled up in weed or bottom detrius when the stick takes it down to the lake bed cos the damn thing may get caught up and not sit like its supposed to do.
Thank heavens for dissolving foam, that stuff is a godsend
Obviously other people may think different, so it would be good to hear their views
