Im trying to decide which set of brake levers to buy for my bike. I am upgrading to bb7's and am grabbing new levers to replace the oem pair.

what im looking at/have:
used Avid SD 2.0L (bought before finding brake set)
used Avid speed dial Ti (coming with brake set)
new 2008 Avid SD 7 (ordered because of the BS in the easton manual about the clamp styles usable on carbon composite bars , can be returned)

any feed back on which is best and such would be great.
