I have some 8-1/2' rods that I keep in the storage tubes. The rod guides will get hung-up going in and coming out, especially on spinning rods. I just started using nylon rod protector sleeves, and these help out immensely. See http://vrxfishing.com/
for an example.
I have found that with spinning rods if you put a little pressure on the opposide of the guides as you slide them in it makes it much easier. No damage to the guides at all.
It's not the heat it's the humility!!!
