Don't know if I was clear. My 1st Gen thumb came off quickly,
but my 2nd Gen does not come off quite as fast. I do not anticipate
having to take off Gen 2 at all. On the Gen 1 thumb I welded
handles onto the main pivot pin so it would be faster to remove. That
got all bent up in use. I still have to pull the main pin and one other
to remove the thumb and a pliers is needed to grab the hairpins. Maybe
30 sec to one minute to remove if the pliers is handy.

In hardcore digging, I am not able to fully curl the bkt with the thumb on,
but I seem to hit 50 lb rocks every 6-in of digging.
