I prefer cold to heat, no doubt about that. I sweat moderately but even in the mid 40s going up, it was pouring off of me. It is the sun exposure below 6,000'. Once you get into the tree up high it's not bad at all.
I have no desire to start that trail at 3 AM to avoid the heat. I found it difficult to be in PS at 6. I'll take the tram in a blizzard any day at 8 AM than Skyline any time.
I guess you might have figured, I'm not a a candidate for C2C...LOL.
