Inconsistent speed in longer putts...
TheSandTrap.com Top Picks
The greens I play are pretty fast... but outside of 30 feet I am very inconsistent with my speed... I'll get it right once... then leave it 8 feet short one hole and blow it 8 feet by the next... any way to fix that? I know practice but for the most part I don't get a lot of time as I work 12-8 or 9 most days.
I would read this thread:
TL;DR - this post post #179 sums it all up quite nicely.
Playing around with how your putter is weighted can make a huge difference too.
Edit* just saw you posted this in another thread:
Shorter backswing and a lot of short game practice... my speed on long putts is horrible... any suggestions
Hopefully the shorter backswing comment is in reference to your full golf swing where a shorter backswing can be beneficial and not your putting, where a shorter backswing will actually lead to a lot of inconsistencies in your ability to control speed.
Yeah, read the thread I linked above. Go to the practice green and try making a backswing that feels too long for your putts and see what happens. Should feel a little floaty but once you get the hang of it you should see distance control improve and likely dramatically.
Without seeing your technique and rhythm it's hard to give a definite answer but here are a few suggestions:
1) Practice downhill putts more than uphill. They are 3-putted more often.
2) Try putting with your rear hand only. This is good practice to develop feel.
3) Make sure you have a consistent ball position and one that is forward of center to promote top spin.
4) Make your back swing and follow through are one motion and resist the urge to have sudden acceleration at any point in the stroke.
5) Consider a fat grip. It may take your wrists out of the stroke and allow you to use only the big muscles of your back and shoulders.
