How many?
How much drop below the "Ladder"?
You said there is an outcropping of sorts that your trying to go over? Is there any chance that you could go around it? Even if you needed another roll of tubing, you would most likely do far better sap wise.
Can you run your line a little higher at the low end of the ladder so you dont have to lift as much ? If you could go from an 5 foot rise to say 1or 2 feet the sap is going to move better.
The reason I ask about taps below the ladder is because it may struggle to get going if there are no taps below the ladder
Finally in my opinion and after some trial and error on my own part and a lot of reading an 11' drop is not very effective on 3/16 tubing, it may even be counterproductive. I would use 5/16 personally on that kind of drop. Also you may want to use 5/16 drops down to your 3/16 lateral lines, according to research sap can travel upwards of 12' backwards in a 3/16 line when the trees freeze up and or shutdown at night, it won't be a big deal the first season but in subsequent years you'll be drawing dirty sap back into your tapholes.
Maybe you already knew a bunch of those things or were already considering using 5/16 drops. If so I apologize for over sharing.
