The only one I can comment on is the Boga Grip.I picked up the small 15lb model and I love it.Its a quality item that has become a part of my gear.I know its kinda pricy but you only have to buy it once as it should last you a long time.Mine gets dunked in the saltwater often and its still good as new.Do yourself a favor and buy the best.Unless you need to weigh large fish the 15lb size is all you need and its half the weight of the 30lb one.
