FishinRod, if you have sandy soil, you may be better sticking with the semi-chisel. The full chisel dulls too fast if you have any sand in the bark. I use semi chisel in all my saws (3 of them) and I did a test with my Dolmar 7900 about 10 years ago. I was told that a skip tooth chain in a larger bar cut faster than a non-skip tooth chain.

So, I took semi-chisel chain, a new loop of skip tooth and regular. Timed the cut with the 32" bar buried in Oak for both loops.

I don't know how big of a bar you need to see a difference, but the regular loop beat the skip tooth loop by a hair. Virtually no difference in cut time.

I found out that if I had the loops cryogenically treated, they lasted longer before needing to be touched up. So when I bought a whole spool of .050 x 3/8 Oregon semi chisel I had the whole spool treated.
