Thank you for the tips!! It is spur and tip bearing.

When I put in my permanent trellis, I'm going to make it 6 feet tall instead of 3 feet like this one. I planted the trees last year and the trellis building project got away from me. My plan is to weld chain links at 1 foot spacing onto a 10 foot piece of steel pipe and cement it 4 feet into the ground. I'll use aluminum "9 wire" or something similar with a ratcheting fence tensioner on each height. I may make the spacing 18" or 2 feet if research dictates that to be more effective. 

Long story short, I didn't prune the leader because this is a temporary trellis.
