Both rangers at Troy are very nice and friendly. One them told me that they are plans to bar off the cave entrance. I dont see it happening anytime soon though. With backmount your dive will end very soon and you might even damage parts of the cave.
I never had problems with cave gear. The only time the ranger was unhappy it was when a couple of OW divers reported me for diving solo and that that my dog was in the water.
I guess a K9 does not quilify as a dive buddy.
