If the thumb is still an issue, and you have a girl throwing heat, then you may want to look into an inner glove that supports the thumb. It might also tighten up those finger stalls as a side benefit.
I'm currently breaking in a cmw3000, and Annasdad is right. The finger stalls aren't large, but they're not tight either.
With a previous surgically repaired thumb, the CMW3000 is a no-brainer! Great thumb protection, you may also want to consider a EvoShield thumb guard to go with it?
