wire for 1.5" line

[sapman]

Does anyone use a single 12.5 gauge wire for a 1.5" mainline? Seems like you might need 2 wires, or go with 9 gauge.

It is definately worth in to go with the 9 guage high tensile for the 1.5" tubing, especially if there isn't a lot of slope. I had to redo some 1.5 because it was originally run on 12.5 and once it got some sap in, it weighted it down and sagged.
