Grip sizing for .610 and .620 shafts

[ZenGolfer]

I am trying to find grips that will create a standard or slightly undersized grip for shafts that have a butt diameter of .610 or .620. These diameters seem fairly common for graphite shafts. The largest diameter grips I find have an inside diameter of .600. Using a .600 grip on a larger diameter shaft will create a slightly oversized grip.
So, any ideas?

Regardless of the grip you put on, it's still having to be streched by the shaft diameter. There are some 0.580" diameter core grips out there, but you're just going to have to stretch them more to get them on. I don't know the answer as far as models, but you'd be looking for the thinnest walled grip you can find, but I don't think the 0.600" core is the measurement you need to avoid.
