what are you using for dist. clamp?

[blazer2007]

Just wondering what to use for a better dist. hold down clamp,I have a b.b and seem to to get a little bit of walk on the timing as time goes by but I don,t want to crank on the hold down bolt too much.I don,t race it so the timing light doesn,t come out to often to check timing.Would the stud type be a better option for a hold down clamp for the dist.
