Which ones are best?

it depends on what you are wanting to do. I have sliders in my wifes, they give some better acceleration and help keep some top speed.

I had 9 gram rollers in it before the sliders, they were fine for just needing alot of low end

Sliders.

Sliders can get your variator open fully for maximum full-range use, even when using lighter weights (depending on the strength of your main clutch torque spring, of course). Their shape form-fits to the space between the variator ramp and the top plate - a roller can't get all the way out like that.

Dyno results have shown that sliders engage up to 20% faster than rollers of the same weight, and many people have reported much smoother and faster acceleration after switching to sliders.

Both rollers and sliders wear out over time. Rollers develop flat spots which lead to jerking during acceleration and slowing down. Sliders already have flat sides on them - which still wear, but since they're already flat the negative effect is minimized.

Hope this helps,

well i kinda want to know the real answer to this question too

which one is better
has better take off
better decelleration
better top speed

I have run both in my wife's. I got better top end and acceleration from the sliders, but more bottom end from the rollers, the rollers were just flat when accelerating, while the sliders you could tell they were working

humm i guess ill have to experiment and see which ones i like i was hoping for a little more top end with the 20's
