I use my guide in the climbing gym where the ropes are quite low stretch all the time, of course the fall factor is low, and it is not in high friction mode. Love it for multipitch climbing routes with a group of three, where two can follow at the same time. I wouldn't see an immediate issue with using them in auto block mode with low strech ropes as long as the fall factor is low. No lead climbs in the high friction/autobloc mode though. Good luck.
Related question - anybody know the parameters which define static vs. low stretch vs dynamic ropes? The old definitions of static vs dynamic were easy - static were fixed ropes for rappelling, caving etc, and dynamic was for climbers and mountaineers to catch a fall. Construction of each type is (usually) noticeably different, and the amount of stretch under body weight was generally 2-3% or less for static and anything greater for dynamic.
Now we have this "low stretch" category, which I'd been led to believe mostly applied to less-static "static-type" ropes rather than more-static "dynamic-type" ropes. But now folks are talking about using low stretch ropes in climbing gyms. I guess I'm a little confused.
