Not unlike a lot of other members on this forum, I buy and sell quite a few bats to figure out what I like and what I don't. A question of most appropriate bat weight is only able to be answered by the individual, as there are a myriad of variables. Swing mechanics, individual strength, bat design, end loading, etc, will all have an effect on the felt weight of the bat. Also, I often feel like a 30oz Easton feels like a 28oz Miken or vice versa depending on the model.
I tend to be a heavy bat fan myself. It's basic physics. As long as you can swing it and make good contact, the heavier bat will create more exit speed and result in greater distance. I spent one season swinging the lighter stuff and not only had a noticeable decrease in distance hitting the Classic M, but also didn't feel like I could control the bat as well. Rather than the heavier bat doing most of the work, I tended to over swing to compensate for the lighter stick and it threw off my swing trajectory.
Again, this is just me, but a heavier bat is better all around for me. You may be different. I'm 6'0 225 and swing a 28oz with .5 endload is what I'm swinging right now.
