i have tried both reeds but on my jetski, and all the results are the same to compare to snowmobiles it has a 951 motor so it bigger then most snowmobiles, i started out with carbon tech and they add a little to top end and thats all i noticed, then i went to v force 2 reeds and they were a big improvement in low and mid range, and the top was even a little better then carbon teck, there were problems with both, after i took the carbon tech out and i noticed the pettles were not seated all the way and i was loosing power when i instaled them in my other jetski, so i don't use carbon tech know, on the vforce i broke 4 center pettals on my jetski this summer and the first problem was the shape of my in takes and i had to report them and that seamed to work, bu i still broke one reed after that, so there is a company that had carbon tech make reeds for the v force pettles and these will fit the skido rered cages also, the difference is there are no cuts in the center reeds so its like a big flap not 3 fingers, they are at www.rossiereng.com you have to call them to get them, but those solved the problem of breaking on my 951, then i got this new used 01 mxzx and it had vforce also so i took a look at them and the pettle on one sider were replace and the others had chips adn were worn out so i replace both with standard stock replacement reeds not the carbon tech ones so i will see how long those last, i hope i didn't mess up buy not replacing them with the carbon tech ones, i hope you can follow what i wrote, some times i skip around because i have so much to say in my head sorry
