V701 should be better, coz T1R is very old model already and not that good to begin with as a UHP class tire. Neo3 & DRB are even lower class than T1R. I'd say at least it wont be worse than any of those! 

You mean the V701? Nope, haven't got the chance to try it actually, coz I have found another better choice which is the Hankook V12 Evo 2. However my assessment above is based on common assumption of tire development in general whereby normally tire technology progress a lot with subsequent new models, hence the older ones very often already several steps behind. I have experienced this with Continental CSC series whereby I had tried the old CSC3 and the replacement CSC5 and the CSC3 was noticeably lacking behind CSC5. So T1R is in this case now. It was never that good to begin with even when it came out new many years ago (it's so long already I even have forgotten how many years this model already in the market), while other tires are already getting more development to come out with newer better performance. So if I were to pick between the V701 which is much newer than T1R, then I believe V701 would be better. But again rather than going with V701 I'd rather pick the V12E2 which has been much more proven (and indeed after using it, I'm very happy with its performance), yet cheaper then V701.
