I honestly don't know much about the current turkey vests Tony, my opinion is that if the one you have is working, doesn't have calls, and you're happy with it, why change?
Things I used to look for in a vest were a fold down WATERPROOF butt pad, plenty of pockets, the ability to cinch down calls tightly so they don't move, the ability to pack a couple decoys if need be, and adjustability in the shoulders.
The only vest I've owned I bought back in high school, it did the job I wanted with very little cost. When we ended up using guns in Nebraska a few years ago I still just used my 2200 for runnin and gunnin
