With that drop you will do very well, having 25-30 taps on any 3/16 line in year 1. How you do in subsequent years depends on how well you clean the system, both soon after the season and then again mid-late fall. After year 1 there will be a "skin" layer left in the tubing which must be cleaned. If not removed that will have chunks scale off next year and will plug the fittings.
I have done well using 3/16 but I learned several tricks or steps to take. Soon after the last sap flow, wash the tubing using calcium chloride. It needs about 30 minute contact time to do a good job, then drain it out and flush well with potable water. (from the top) Then in mid to late fall, repeat. I also swap out every 3/16 fitting. I use 5/16 taps and drops, then all 3/16 laterals. Thus I use a new tap, tee and any connector in the line is changed for new. Mine are all also on good vacuum (26-27") and the connector before entering the mainline (a 3/16 x 5/16 connector) is changed. I've had good results doing this for 5 years now, but 2020 was down a little. 2016-2019 were all real good. This year I'll repeat the same.
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.
