I've got the yips - I use a 54 SM9 10s - I do have a 58 in the bag as well with more bounce and a 50 similar (only really use that for full shots).
I did try the Cleveland chipper thing last summer that helped a bit but my mates took the mickey so much - 'grandad chipper' amongst other things - that in the end it had to go. In the meantime the handicap has gone up about 4 and I'm thinning and fatting at least 4 times a round.
Any advice ?
