OK Erick, you talked me into it

The first clip here is way less than ideal. I wanted to bury the bars, but didn't have a good piece of wood to do it in. So take it for what it's worth. I didn't realize the bar wasn't all the way in the wood on the first cut of the 7901. Oh well. A couple things are still pretty clear though.
1. The 7901 is still fastest under both normal and max loads.
2. The 390 is a
hair faster than the 660 under both normal and max loads. I'm talking like 0.10-0.30 seconds.
3. All of the saws made slower cuts under max load than normal load, where as they were all faster under max load with a 7-pin.
4. Bottom line, the 390 and 660 are still very comparable.
5. They all pull an 8-pin rim well in this wood with 24" B&Cs.
