Agree 100%!!!
I got an Aviar P&A (173g) when I started playing disc golf back in September. I did think of it as a beginner disc so I experimented with many putters: Pure, Ringer, P2, Swan 1 Reborn, Judge, and Aviar Classic. Liked each of them for a while but kept coming back to the Aviar P&A.
Lately I wanted to move away from this "beginner" disc (even though pros use it) that so many people use, so I looked for a clone and the Warlock came to the forefront. It is almost identical to Aviar P&A in shape, although each of the two Warlocks I bought have a slightly different shape from one another.
I have the Warlock in the SSS plastic and it feels much better than the DX plastic. To me the DX plastic releases a little smoother on longer putts but the SSS feels so much better, especially in the colder weather. I will say though that the SSS plastic shows much deeper dents than the Aviar P&A.
Interchangeable disc? Almost - the Aviar seems to have a little more room on the bottom part of the lip which seems to make spin putts easier to throw (at least the way I hold the putter).
Right now the Warlock is definitely growing on me day by day! But right now, 35' putt with a buck on the line, I'm reaching for the Aviar DX.
Would like to try the Aviar P&A in the R-Pro plastic and the Warlock in the S plastic...so maybe that will be my next order
