I tried to simulate a cap by adding 10g around the head, focusing at the sides. It felt and looked solid, but when I went to the court it lacked maneuverability on the 1hbh side. Serves were very heavy, thought, I really liked it.
I'd added 3g at the buttcap to conter balance, but I'll add 3 more. Total weight is now 370g, with 1.20 mm Toalson syn gut, fairway leather, 2 gamma overgrips that dont reach the end of the handle, sampras O dampaner and the "cap tape". More HL than before. It weighted 354g before adding tape.
