Not sure what to make of this.
I will say I like the double hook idea. You lose the DH when you remove your starter. If nothing else that'd get rid of the "opener" nonsense.
I think smaller staffs is the way to go. There might be secondary benefits here of reducing K's and getting more balls in play, which needs to happen somehow.
