In reply to Uluru: I understand where he's coming from..but a couple of points
A) he's not 'slow' in getting to that stage, it takes time, his technique needs time to devalop etc
B) the more you get grade obsessed the less likely you are to get there..climb you're current lead grade and step up when you're ready, forget 6a etc just let it come and you'll get there!
C) If progressing quickly is really important, maybe take a session or two a week to work on technique, at this stage it's almost certainly the reason 6a isn't attainable yet. OK maybe a powerful climber could power through a 6a but technique is usually the limiting factor for begginer/intermediate climbers, learn how to do precise footwork,fluid movement, clipping with a straight arm, flag moves, drop knee moves etc these are really important on steep indoor routes, a good flag move or knee drop can really make a move less hard on the arms and allow you to climber harder than you currently can! And make a concious effort not to power through moves!
Build up technique and let it come, it WILL come!
