i have used both. they are ok they both have nasty pinches but durability is an issue.another thing is if you have an x-3,v-groove,kannon or any othere head that is on a cs it must be on a crank shaft or it wont work as well. unlike other heads that are offset this head is onset, meaning it bends forward
Hey cant the CS heads not even fit on the regular shafts or is it they just cant work on htem that good. I remember hearing they wont even go on them but....maybe i heard wrong.
