I have the same problem , with the swelling of my fingers to the thumb. Sometimes they change like night and day in a three game set. I use vise it thumb with an extra bigger slug for when swelling occurs. As for fingers, I buy grips in bulk online in a couple of different sizes. I try to time the swelling of my fingers, usually when the weather changes. (winter-summer, summer-winter) Thats my system I hope it helps.
