Ok, i thought i'd bring back an old thread rather than start a new one... I see there are varied opinions on the GRP vs V-Spec topic... My question is, is there anyone who can give me a comparison between a GRP 21MRT and an OS Speed? I've been running a speed for about a year now, (I have 2 actually) but i was interested to try the tuned GRP.... Any thoughts?

Cheers....TIA!
