Tried Gulp for the first time last year, now its a go to in my box, and it lasts on the hook longer than a real worm, which is great for trolling. A Vibrax BlueFox and gulp caught alot of trout this year, including an 8lb'er out of Dragon Lake in Quesnel (Willowleaf, weddingband & gulp).
Had huge success with it in Jones Lake last year. I would recommend it to anyone over powerbait (I've had very limited success with it as well)
