In reply to pec:
I’ve assumed the OP knows about which end to use since she says she already has a set of sort draws...
Agree with this...
“Any burrs on a blue krab aren't a problem when it's clipped into a wire...”
I don’t agree with this though...
“...and to be honest even when it's occasionally used to extend a cam sling as it doesn't rub over it in the way that a rope can be dragged some distance over a krab during a fall.”
I understand what you mean about the sling not moving in the same way as a rope, but skinny dyneema slings are fragile (although very strong) and I’d be distinctly uncomfortable clipping my bolt end draws with significant burrs to slings (including on cams & hexes).
Seen significant damage to the inside of sturdy indoor in-situ draw tapes as a result of the maillon rapide rotating and putting the burred end in the draw. Admittedly this is a scenario where the loading is consistently in the same place (and probably sees more continuous use than a personal rack) but even so.
Of course occasional use on the trad rack may not cause a catastrophic failure, but if it does nick a cam or hex sling the OP will spend as much or more on re-slinging than they would on a handful of budget snapgates that could be swapped out with the bolt end karabiners for trad climbs
