Even though I like a snug thumb, I have to say that "shoving" the thumb in sounds too tight, even for me.
What that causes is excess friction, which causes callousing, which changes the size of your thumb making it larger. If your hole is too tight, that becomes a never ending cycle ( Take it from experience. I have to "sand" my calluses down with a pumice board occasionally )
For me, the perfect thumbhole size is where the thumb just slides in smoothly without leaving any space on the sides, then using tape to adust the front-back fit. To achieve this, I use oval thumb sleeves.
When I forget to use the pumice board on my calluses, my thumbhole gets "shove it in" tight as well. When everything is right (for me), I have to blow just a touch of moisture into the thumbhole to creat the "snugness" I like.
For me, with my arthritic thumb joint and resultive reverse pitch, I need to keep it pretty snug so that I control the release point without losing it early.
