Yeah, with solid hits just think about the sound off the bat when you really connect on a pitch. If you raise solid hits, you will get more solid contact and give you faster ground balls, more line drives, and less weak pop ups and choppers.
I've found that putting solid hits up to 6 (+1) and lowering power to 4 (-1) you get pretty good results. You still get some good hits instead of a ton of choppers and pop ups, but you aren't going to have an unrealistic amount of homers.
