I originally thought that I'd go with the K-45, but ultimately went with the K-60 as I like power, not because I use it, but because it's there if I need it. Density altitude is rarely a concern here in Phoenix as I don't do much flying when we reach our high summer temps. When we head north for high mountain (6-8K) temperatures in Idaho DA is important, thus the power of the 60 becomes very important. Yes, I'd go with the K-60. Two other comments: I laid a small piece of BVM ceramic blanket between the smoke tube and the foam fuselage (even though it has a foil liner) simply as an additional layer of heat protection. The heat can wick from the heat source-thus the exhaust. Next, I marvel at the technology of the new GSU. It's like looking at a digital flat screen and super easy to (touch screen) use. Lastly, if you folks are not using the AutoDens app, try it. It'll make your flying a 'bit more enjoyable
