Without getting into an almighty debate its very hard to say categorically which springs are better, unless the same individual tests both springs over a certain time period from when they are brand new.
However in my
own opinion, taking into account what users, testers etc have reported back to me...
I feel that the Carbon/Fibre mix springs are at present are proving themselves to be better than the fibreglass springs we use to sell and could prove with time to be as good as any springs out there if not better.
We have never had a problem with the fibreglass springs, they were responsive and did their job well however the Carbon/fibre mix springs are much more responsive, giving a better return for less of an effort and more height as well. The other reason why I feel they edge the older ones is we have only had a few break in almost 5 months.
I know Paul Self on the forum has been using the new Carbon/Fibre mix springs so you could ask him his opinion as well
