Im still using my Prince 52 X 50 that I used during my test period. I plan to put on a repitched 52 X 54 Prince and try it before sun n fun to see if I like it. I need a bit more pitch to take advantage of the powerband I have. I tend to cruise at somewhere @ 65% power doing 150 on cross country flying - not bad really - but that is mostly becouse I think I am close to overreving the prop. With more pitch I should cruise faster. My climb rate did improve considerable though with the gap seals. The Warp drive does provide a lot more static thrust but not as much high speed thrust as the Sterba prop does. Dont confuse what it does on the ground to how it acts in the air. My Prince shows very little static thrust compared to many but is built for higher speeds.
