being a finger man myself both trad and wheels (at one time) I will tell you to go fingers.
Accuracy is faster gained by a release, more knowledge and an intimacy with your equip will be gained faster with fingers....Then again its more in how much time you spend behind it. Fingers, less to go wrong! Release, fingertips dont freeze off at -30 <img src=icon_smile_wink.gif border=0 align=middle>
