Leader evaporator

Headed to Rutland Vt store next week for my supplies. 1st attempt at using tubing to replace most of my buckets.70 ft mainline into sugar house tank sytem. Then one 100ft arterial w/ 75 taps and a 2nd 150 ft line w/80- 100 taps.
I want to put a dumping station on the shorter line to bucket some trees not inline for the gravity system, maybe 30 buckets.
Any suggestions encouraged, ie taps reccomended, how many taps you can run on a 3/4 inch arterial line.
from the back of longest run to tank is probably a 20 ft drop in elavation
thanks

I know you say you got a 20 ft drop but not sure on the entire length of your mainline. But anyways for 3/4" less than 5% slope max of 400 taps and better with max of 300
5-10% slope 300-500 taps
10% or greater 300-600 taps
So by the sounds of it you will be fine with 3/4"
Good luck
