check out the Nunchuk shaft, at 104grams it would be easy to get the specs close to that. I have been using this shaft for about 10 years, I did experiment with a setup about what you described but the Syard T388 head was too low spin for me. I wore myself out trying to get the extra speed to make it effective, but gee it was long. If I had 2 more degrees of loft it would have been perfect. The actual spec was 205.6g head, 43.88″ shaft, D3, total mass 356g
