I agree, and also the bigger the profile, the more that has to be taken away from somewhere else. Then you end up with a huge shape but with very little wood behind it (a la L&W or Fusions) which makes for a very unforgiving profile.
I've always desired a huge bat, and have used things like Jokers, but the I've found many to simply be just too heavy. i really can't use anything bigger than a 2.10, and I find that a bloody good batmaker can make you something reasonably chunky without too much concaving for that weight.
