Happened to me today, was using my GN Warner Kaboom after feeling guilty for wasting willow, was on 40 odd after 24 overs opening. Had hit a few nice shots and felt decent, but wasn't using it to the full potential. Swapped out to a Phantom Performance bat in the Dark Edition shape, and pinged 2 of the nicest sixes I've hit in a long time. The Phantom had never seen any action before, and I ended up on 86* after 39 overs.
Long story short, need a bat with the meat around 3-7 inches up from the toe. Oh, and helps if it's TK made. Was playing on an Astro with decent bounce, so agree with regards to folk adjusting to a pitch, more than adjusting a bat shape for a pitch.
