In reply to Rob Greenwood - UKClimbing:
That's interesting. I would usually go with the same rubber a shoe came with for resoling but as I couldn't get my blancos resoled in stealth I was recommended to try the unparallel RH rubber over the XS grip2.
I don't know if it's just me but it feels like the stickiest rubber I've used and is still reasonably durable (obviously not so much as the harder compounds like XS edge).
