I wished I could have known you were going to change the fibers I would have sent you some OEM ones just so you did not have to mess with them Barrnet POS fibers. I also would have recommended the MTC ones. But I am sure I have some great used ones that have hardly any miles on them. Stiffer springs are good. I hear as the Barnet fibers heat up they tend to drag whenyou putting it in gear and when your shifting. Just something I heard on these sites 125 buck for MTC one and Like I said anyone goes to change theirs let me know I will send you soem OEM ones for the price of shipping. I believe I even have a new rear one which has a different ID because of the anti judder spring and seat. Anyway not meaning to kick your work I have heard great things about other Barrnett products especailly their cables. Just passing on information I have gathered from the sites, and I suppose I should shut my mouth because I have never used them myself because of what I heard. Le tme know if I am wrong after you run them a while so I do not put my foot in my mouth again.
I also heard you can use some of the Busa fibers as long as you get the stack height right. I guess the busa has two different thickness fibers. Oh and I heard the Barnett steals are great just negative reports on the fibers.
