I find the GP great on my OHBH. If I'm going to mishit the ball, it's going to be more on my BH side (probably due to swing mechanics and fitness which makes me late to the ball more on the BH side), and for that reason, I think the head shape of the GP (and the Prince Phantom 93P, for that matter) helps in this area.
I use two overgrips (in addition to further weight mods both in the head and handle), and therefore, my racquets have a more HL balance (315mm strung) which I feel also helps with what some might call sluggishness. I have no problem with the GP being sluggish on either side (FH or BH), it's excellent on volleys and overheads, and I serve very well with it.
I too was not a huge fan of 100 sq. in. racquets as they felt less precise, but I was pleasantly surprised by both the GP and SP. They are still not the same as the G360+ PMP or Yonex VCP 97HD (or Mids for that matter), but are the closest I have tried.
How much weight did you add to the handle and head ?
