10 tooth to 8 tooth drivers?

[chrispy]

I'm switching out the track on my '06 summit going from a 2" paddle to a 2 1/4" paddle. I'm sure I'd have to go to atleast a 9 tooth, but would I be gaining anything by going to an 8 tooth driver. I plan on clutching the sled anyway so I'm not too worried about that aspect, but would I be giving up too much top/track speed to gain the extra torque of the lower gearing? Would the increased rolling resistance of the 6" dia driver(8 tooth) compared to the 8" dia driver(10 tooth) be a hindrence or should I just go 9 tooth? I mostly ride in fairly tight trees and climb not too much. The gearing is stock at 21/45 and ride at about 6500'.
While I'm at it, has anyone had any experience(good and bad) with single sided extrovert drivers? That's what the dealer is trying to sell me saying that they are stong enough for anything but boost applications. They look kinda chinchy to me compared to the stock double sided ones on my sled. This was also posted in the REV section, but I wasnted to hit a broader group of riders to get more opinions.

going from 10t to 8t drivers will gear you DOWN quite a bit.

also it may not be doable since you loose more contact area since the suspension mounts will be alot higher than the top of the drivers, for this alone your best/only bet would be to go with the extrovert drivers.

If you could get away with 9t I would run those.

But like stated now your gearing/clutching/speedo will now be affected.

go with the 9 tooth extroverts. The bigger you can run the better. I have an 06 with the 2 1/4 paddles and run 9 tooth drivers. Also im also geared at 19/47
