Pretty similar to what
@blablavla said. It's like the MP was perfect as it was, aside from the control aspect, once you add lead, you either lose it's lightweight feel and it becomes maybe too powerful, or you counterbalance and then it stops being a lightweight frame and moves into exactly what the Tour is, but you don't have the control of the Tour, because the MP is already generating decent spin and power, and then you add lead it over does it but doesn't have the control to back it up, that's what i thought anyway. It could be the strings I used was too powerful, could of dialed it down
I don't know if other people had the same experience, maybe it's because my wrist is more sensitive these days, but i feel that many of the Head 360+ models are string sensitive & tension sensitive. Anytime i put a stiffer poly in these 360+ head racquets, like a Lux 4G, or a Weiss Cannon Ultra, the flex seemed to become more hollow, tiny and lose it's great feel. Also for me anything over 52lbs (more so 48-50lbs) was not great unless i used a softer poly or hybrid
String choice when it comes to the Tour or Pro is more about what launch angle you want and if you need enough spin. I currently got a set of Head Lynx Tour in the GTour and it feels really good and spin is perfect.

Also with the GPro's weight, i would use 1.15 gauge to remove a few grams off the head of the frame, which would reduce the swing weight and make it easier to swing, and at the same time fixed the launch angle that i wasn't used to, that's when I connected with the Pro and immediately played the best I ever played
I don't think you can really go wrong with any of the Gravity's, i think they are all good for a certain level or purpose. Been using them since day of the release, and I've bought at least 10 new models of other racquets since for fun, that were also very enjoyable frames, but nothing I've found just matches up with the feel and forgiveness of a Gravity. The shape isn't for everyone, but for those who like it, nothing can quite compare
