It is different every month. This summer it was a Star Teebird. At the end of the summer it was my X-Link Ridge. Yet all since June a Star San Marino Roc has never left my bag despite my aversion to Rocs until this year (because of its bead). Currently I cannot play without my Rivers. I am also trying to make my new dyed X-Link Ascents my winter go-to disc (and possibly full time complement to the River).
