Leader is supposed to be developing those.

I started my own test this year. I kept track of how much sap I gathered from each bush. Next year I'll use adapters in one bush where the tubing and spiles are about 7 years old. I'll do the math for each season to see how much sap I got per tap overall vs the bush where I've used reducers. That should tell me if it makes sense to buy new adapters every year.
