I am looking to upgrade my old putter, which is a 39” Cleveland Classic Almost Belly putter which has a 36″ shaft, 400g head and a Super Stroke 17” Flatso grip.  I like the feel of the club, but would love to move to a 38” shaft and I like the idea of adding some shaft weight for stability.  If I paired the PTM-4 putter with the weighted Pure Track shafts at 38”, would that be too much weight overall (with the same grip)?  Does anyone else have experience using the weighted shafts at that length?
