I used to use midsize grips with 3 layers of grip tape. Ive always just used grip tape and buy it in 50m rolls 2 inches wide.
Now Ive changed to jumbo size grips with just the one strip of grip tape, it sort of feels like having to bite the bullet and go up a waist size with your trousers.
I should have done that years ago really.
One for trial and error myself, over the years I've discovered that 2 layers of masking tape under the grip tape is what allows my grip to feel the most comfortable. If a standard grip feels too thin and midsize too large, I'd start at this point
