Tophat answers

I have been reading til I went cross-eyed trying to find info on the difference between a talon tophat/valve and condor tophat/valve. Many places I’ve seen that the only real difference in the 2 is the throat diameter of the tophat. Can anyone confirm or correct this info for me?

Also how is the tophat removed on both guns? Trying to gain info for myself and 2 friends who are all new to the AF line of guns.

Thanks in advance
