Hello All - Recently purchased TSi3 with the standard 45.5 length shaft. Liked the shaft but still hit my 915D3 better. 915 has a 44.5 playing length and the head has a 14g weight (standard is 9g?). In any case, I imagine I need to reduce the head weight but trying to understand how much is required when adding 1 inch to the playing length. I tried the config with no head weight changes and I am hitting a block fade so I am curious if a weight change may fix that (of course that could just be the way I am swinging right now).
