PSUAthI suspect that no more than 1 in 5 strapmakers offers QR spring bars at all, and even fewer do it standard. Couple years ago I'd have said 1 in 10; I am seeing more. But still, they're far from the norm. Especially in this market segment. Heck, Bulang and Bas & Lokes don't offer them, and they're both rather higher-scale.
