I have marta SL's on my RIP 9, Juicy 7's on my Socom DH bike. I also have Juicy 7 carbons (gotta smokin Deal) on my One 9, and formula K18 on the DOS. My favs are the Marta's, Bling is hot and they work really well, juicys are a better value and I have heard from a lot of peeps that some have problems with the Marta's... Mine are great Good luck you really can not go wrong either way
