I use the B2 squids. The new Tsunami's look nicer though. I have so many B2's (boxes and boxes of them) that I will be using them for the rest of my life.
The Gulps are effective but kinda steep on price. I've been using the B2's on my ThomCat Fluke Rigs for 11 years and find them relatively durable and much more cost friendly. Good luck.
