Donnie, I think a 300 size crankbait will handle a dressed rear hook just fine. I've played around with hook size on 300's mostly and haven't had any problem with any size I've tried on them yet. 100's and 200's may need just a little less material back there to get them to act right. I run a red rear hook on all my crankbaits now but with your dressed rear hook containing multi colored hair and flash, hook color under the dressing probably won't be as critical as just a bare hook.
