As stated above, Teflon caps have a sound that you may or may not prefer (as does every cap). I'd take @welcher's advice and call the former CJ tech for professional input.
I personally prefer copper foil (and have duelund caps throughout the system), but haven't listened to the most expensive copper teflons. The vcap odam's are also possible upgrades that have received great reviews and might be worth a shot. They're on my list to try.
