A combination of maples is good. I tap mostly sugars, but at one woods I have about 25% reds, at the other it's all sugars. As you get towards the end of the season, watch the buds, the soft maples open bud a few weeks earlier than sugars. You want to pull the soft taps when their buds open, then keep going with the sugars until they open. Last year I got 3.5 weeks on the sugars after the reds popped, more commonly it's about 2-2.5 weeks.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
