If adding weight makes the frame feel sluggish (*that was my case with racket modification before my UT), how about using the 1/4” lead tape and add weight (*maybe 1 gram) a little at a time? I initially added 1.5 grams @ 12 but added another 1.5 grams for more SW because the added weight did not negatively effect the maneuverability. I just feel that the frame doesn’t need much weight in the head (*just adding 3 grams @ 12 provided depth I needed) but need more weight in the handle to provide more heft and plow.Added a 3.6 gram lead sampras lead strip at 3 and 9, now 340 grams and 6.2HL. Restrung with 1.25 Alu Power soft at 53 will see how it plays.
Maybe you might want to use more powerful strings like Element Rough 16G.
