Hmm? Is mid size larger than standard size? When I tried larger than my size, the right arm Flying Wedge seemed less wobbly.
I believe Golf Pride shows their mid-sized to by +1/16" compared to their standard. Many of the guys I play golf with have picked my clubs up and the initial reaction is "what's up with the big grips?" But a few eventually switched over to them as they start to appreciate the "secure" feel it gives you once you get used to them.
