I've noticed that mine seem to be a bit stubborn in the warmer weather. The more I take them in and out, the easier they get. Friday I was really struggling to get one out (first time in new ball) - even tried the tape to get a better grip, when one of my team mates handed me a tool (I think it's called Change-IT) that you insert into thumb, twist and pull out the insert. Worked well and didn't strain my thumb doing it. Going to see about ordering one when I get back from vacation.
