I've added about 8g of lead to the handle, so that, plus the overgip brings the total additional weight in the handle to about 13 or 14g. By my calculation, this should make the racquet right about 9 or 10pts head light.
I haven't added any weight in the hoop yet. I'm going to give this a try and see how it feels.
Back when I used the T-7, I had success with this exact setup: 8g of lead in the handle, none in the hoop.
Will report back next time I am able to get some court time with it, which will be either Sunday afternoon or Monday morning.
