Any advice for a "hybrid" goalie?

Do yourself a favour and pay for a private session with a local goalie coach. It's worth way more than the little money you'll spend.

Wow 5 times a week for a year and a half, that amounts to more time in net than people who have played twice that long. Ive been playing for something like 2 years. For about 6 months ive been playing 2 times a week, before just once. Makes a huge difference playing more than once a week, you just cant improve only paying once a week.
Ill let others give you advice about what style to go with, but the only question i would ask is have you taken any time off?
Playing 5 times a week for that long without a break could be detrimental to your progress. I have always found that if i take a break from something i come back much improved. Im not sure if its a documented truth, but i firmly believe that you reach roadblocks in your progress even if your not aware of it and the only way past them is a break from what you are doing.

I agree with Chewbacca, and not only because it is what I do. A good goalie coach is worth much more than what you will pay. I promise you it is worth it.

In my current session, my instructor has been stressing save selection. His theory is to not limit yourself to a "style", but to do what works to stop the puck, a la Tim Thomas. If I had to pick a style, I'd also say I'm hybrid, but I've found there are not a lot of true "butterfly" goalies in my levels of play.

I think the first thing you should work on, and a lot of the time is the first thing new goalies are taught, is to always be square to the shooter and the center of the net. Back yourself up into the net so your ass is on the center pipe, rotate yourself on the center pipe to get square to the shooter and come out straight to the shooter. This will always give you the proper positioning and thats the most important and basic thing. Once you the angles become more natural you can start to offset yourself to your weeker areas, like your stick side or whatever. I was trained as a stand up goalie, but for a while ive been playing a more hybrid style, using standup style for shots from farther out and the butterfly style for shots in close or through heavy traffic

Good Advice JohnnyZero.

I coach as well, and my advice is not to worry about style at this point. Even the most hard core butterfly goalies will use other technique when called for. My advice is to do exactly what you are doing. Face pucks! Learn as much technique across the board as you can. Learn butterfly, learn the Vertical/Horizontal, the 1/2 butterfly, how to stay square to the puck, angles, depth. Learn how to read the puck as it leaves the stick.
What you want to do is learn as much as you can so that when a shot is released, you are as close as possible to "the right place at the right time" from there, your body will naturally make the best save selection in your bag of tricks as possible based on muscle memory and experience. This​ will become your "style".

I've been able to talk to a couple goalie coaches(the only two I know of are heavily involved with their respective teams at the moment). Our team has a "coach", he used to coach at the high school level when his kids played, so he has a few tips here and there. I appreciate everybody's input. Lining up with the post and then skating out is something I'll have to try
I took sometime off during the summer, cutting back to once a week or every other week, to pursue a new hobby. (Golf, oddly enough.) I'll be forced to take time off again as I dislocated my shoulder last week. Huzah.
