There is a large group here in the forums that refer to themselves as Dive NY.
You have a real nice quarry (I know I have real and nice and quarry in the same sentence, and usually that doesn't go) not too far away from you. It is Dutch Springs.
Dutch Springs
My understanding is it is very close to NYC.
Hook up with those guys and get more dives!
As for your rig, I switched to nearly the exact same one very early in my career. I too would get comments. You'll figure out most of the people that makes those comments tend to be morons anyway. Ignore them. I found it is better to just change the topic.
One tip, make sure that your dive buddy knows where to go for air. Most new divers are trained not to go for the primary of their buddy. If you have a regular dive buddy, pass them your primary at a safety stop or something easy and safe. You may find they are making the switch themselves.
Good luck!
