Hi Al, I just ran across my spec sheets on Pegas and FD blades. Pegas has super skip blade.
FD Polar #1 - 26 tpi
FD XL #1 - 24 tpi
Pegas Skip #1 - 22.7 tpi
Pegas Super Skip #1 - 17.2 tpi
I would check my Olson chart but it is in the shop and it is cold outside, 23 degrees and about 50 in the shop.
Huge differences. Now I realize how important these charts are when trying to compare blades. The manufacturers do us a great service with these charts.
