150ft putter is seriously overpowered. after tibbets and i hit over 50 putts from 60-80ft, i can say (i guess we'll see what tibbets will say) that the putter is about 80% stronger than it should be.
putts from 85ft with downhill about 6inches and 6ft left to right break. are hit with 10ft power (based on a 30ft putter config). or a 50ft putter speed.
that comes to 80% stronger
we did many from 75ft, with 8ft speed and got inside 5ft every time
it is consistent. others can feel free to try it to verify
