It just doesn't seem to be as "bulletproof" when it comes to piercing it with the needle. All velcro, regardless of make model or vintage is a total PITA to sew, it's just a matter of degrees, the quest style omni-tape just seems easier to me, it's obviously made slightly differently, if you compare the two side-by-side.
I *believe* the quest stuff is lighter by size, but honestly, I haven't used the "velcro" brand stuff in so long I can't say for sure. The only problem is that the stuff from quest only comes in 1" variety, but it's real easy to cut in half.
I'll try to remember to weigh a yard of the quest omni-tape tomorrow in the shop.
