Hello all! I've finally got some extra money (thank you GI bill!) and I'm pretty set on the wbbb. I just need to figure out which is best for me. Strength is important, since I'm a "hearty" 300lbs. I'll be doing the majority of my hanging between late spring-early fall (so basically summer camping).

I just want to know why the $20 difference in the double 1.9/1.1 and the double 1.7? A bit of a weight penalty, but is that it?

Thanks in advance!
