Hi
This year i made the mistake of binning my beloved 906 f4 15.5 with ys6 for the bells and whistles of the 910f 3 wood.
After going through custom fitting i was surely good to go - what could go wrong.
Months later - After trying every possible setting on surefit (after i purchaed the tool) i have a club i just could not make work on the golf course. Shaft (red diamana still) very inconsistant.
Alternative shafts cost a fortune ie £180 for a fukuki .
So god bless e bay - on lookout for 909 with ys6, diamana blueboard or fubuki and using old steelhead in mean time.
New isnt always better
