Ditto. I tell this story all the time. The day Mike and I took Aaron's class, we went to the Farmington afterwards. We hiked in through the snow. When we arrived, I rigged up the leader per Aaron's specifications (we also made one in class), and put on a tandem rig like he showed us. At the time, I remember tying on a cased caddis and a stonefly. On about my fourth drift I hooked up with a nice holdover brown! Mike and I were amazed at our new found success. This was also the day that I bought my 10ft 5wt Z-Axis, again per Aaron's recommendation. Take the class, take notes, write down the formula and ask about MENDING (the key). To this day I use the same leader, but I never give out the formula to anyone. Aaron and I call it the "TPO leader."
