In reply to Paul Crusher R:
I think I was considering them too, but decided to go for DMM Phantoms. Even with my 'medium-at-best' sized hands I don't find them [phantoms] particularly easy to clip (I clip with my thumb though, so maybe it will be different if I used another clipping technique).
Might be worth just getting a single 19g QD and trying it out for a while to see how you find it.
Edit: just read you want to only use the 19g for the gear end. In that case that's a clever idea! If I did that I'd save 70g over just having 10 normal phantom QDs in that case, not a heck of a lot. (can probably get a 100-200g saving more easily from a new harness or helmet)
