The e604's are really good Tom mics. You will not have to upgrade in the future, ever.
I got the 504's (the predecessor) in the mid 90's and used them on everything up until I stopped recording last year.
Besides the built in mount, their size makes them easier to place than some mics. I made myself some mic cables with right angle plugs to keep the profile even lower.
The mounts are removable, aren't they? Have you tried them on anything other than toms or snare?

Also, have you used them live? Do they seem sturdy enough for live use?
