Dbl, bladed inlines should not use dp. cup colo. they spin to close to shaft and actually vibrate less than std. or aspen type.Clevice size should be one size lgr. and interlocked.Min.of 2 solid metal beads I like glass/metal combo 2/3 beads.Look for the sm. flared body in nickel Mepps uses it at front of many baits helps start blades. Experiment w/blade sz.body wgt.I Like heavy bodies in bigger water for obvious reasons and larger dakotas fluted royals,wide willows and french are my favorites.Dont finish your front line tie loop and you can switch until its right.slow willows easier to start than std. good luck .
