I have a Knight Disc Extreme and I shoot 110 grn T7, 2f, with a 250 SST low drag, red sabot, not the stick one. I just also want to say that 150grns of T7 pellets ARE NOT the same as 150grns of T7 loose!!!!!!!! It will blow the hell out of your gun!!!!!!! Loose generates approx. 25% more pressure than pellets and thats why they claim the max is 120 grns of loose T7.
