I have the Omega with a composite stock. It took some getting used to, but now I find it comfortable to shoot. I actually changed my 1X red dot to a Viper 6.5x20. Here in Utah they changed the scope restriction this year. I am taking it up on a late deer hunt leaving Thursday. I used to shoot the Power belts, but switched to the Hornaday SST in 250 gr. and am actually impressed with them. I tried many different powers charges and I ended up with 130 grains of 777 (2 - 50/50 pellets & 1 - 30/50 pellet). I got my velocity and it is showing an average of 10 shots at 1720 FPS. Not the fasted, but pretty darn accurate. I created a Muzzy gun in the app (Shooter) and put all the info in and then dialed to 276 yards and was able to hit a 20" steel plate 2 out of 3 shots. If you change it and don't like it you can always change back to the original stock and sell the thumbhole. Good luck.
