I use the Prestige Pro (PP), red, 360+, 95 sq in. I've been using it for 16 months. I've never tried the Prestige Mid, 93 sq in, but it's heavier, and I've heard it's harder to use than the 95 sq in. You can order the 93 sq in from Tennis Warehouse for $119. My first session with the PP was a demo and I was hitting the court in the exact spot I was aiming for. I thought it was a bit heavy, but thought it wasn't too heavy. I loved the stability, precision, control. I thought it had enough power for me. I returned the demo and bought one. After a few sessions, I didn't like the weight (too heavy) and the small head (for defense and volleying). I tried many other rackets, but always came back to my PP because it was better. I almost switched to the Wilson Pro Staff Six.One 100 v13. It has pretty much the same control, precision and stability, but is a little lighter and has a bigger head. I went back to the PP because it's a little better.
I've tried many strings (I always use poly/multi hybrid). The best string I like is Solinco Confidential 1.25mm in the main at 50 lbs and Head Velocity natural color 1.30mm in the cross at 54lbs. The Confidential has an amazing combo of power, feel, and control. It's actually a pretty stiff string and that's why there's a lot of control, but it feels soft and powerful. I'm not sure how Solinco accomplished that. And it's not too expensive. I am going to try some other strings soon, but I have a feeling I'm going to go back to Confidential. And I'm always using Confidential during league and ladder matches. I've never tried ALU Power, but I'm guessing that string is pretty soft, for a poly. Maybe go lower tension. And/or maybe try Luxilon Element in the cross. Element is really soft, maybe Luxilon's softest poly. Emma Raducanu uses ALU Power in the main and Element in the cross. When I used a stiffer string in the past on my PP the ball wouldn't go anywhere on non sweet spot hits and it felt harsh. Now I get some power on non sweet spot hits, enough to get it over the net.
One other racket I tried recently that I like a lot is the Wilson Clash 98. A lot of control, stability, feel, and enough power. The PP is better though.
I'm guessing your previous racket was the Head Graphene XT Radical MP. I believe that racket is stiffer than the PP. In my opinion, the graphene 360+ is stiff (graphene) in the right places and flexible (spiral fibers) in the right places to give great power, feel, stability, and comfort.
I tried some lead tape on my PP. First I put 2 grams in the handle. I was trying to make it more maneuverable. The added weight made my serve faster. The racket was slightly more whippy, but I lost a lot of stability and control. Then I added 2 grams to 2 and 10 o'clock and left the 2 grams in the handle. The stability and control was still very bad. I took all the lead tape off. I believe the racket is best without any mods. My PP is 307 grams without strings and mods.
From videos I've watched the PP has been called the most precision and control racket (Tennis Spin - referred to whole Prestige line), the most stable racket (Mike Komen - referred to PP), great control, stability, and pinpoint precision (TennisNerd - referred to whole Prestige line, but he prefers MP).
