instincts might be a bit aggressive if you have not climbed for a couple of years, I would think about 'Vapours' if you want something with a bit more performance than the reflex but still relatively comfy. I would be cautious about buying shoes online without trying them on.
Caveat Emptor.... I get on very well with Sportivas (Miuras, Miura VS, Katanas), pretty well with 5.10s (Anasazi Verdes / VCS, less so Blancos), but Scarpas do not fit me at all well - bunch up my toes in a horrible fashion.
