Got a new set of Fast Guns. Boy are they nice. I'll check back with up dates on how they are working and how they hold up. They look to be a top quality product.
Absolutely the best in my opinion. Mine came with stick on decals to identify each one in it's position, however, small changes in how the camper sits in the box usually means a turn or two on the hook to adjust length to perfect tension.
My fronts are a bit more than an inch different from my backs, so I just use them that way.
