wrappers or not?

I'm also in the camp of "store them as I buy them". Only exception is that I take the cap off aluminum tubes.

I'm confused. Once you have cut the cap and lit the other end, doesn't the aluminum tube heat up pretty quickly?
Does it not ? or Do you use some sort of Cigar holder to avoid problems?
Expect the tobacco inside the tube would burn well, surely the heat would not melt the tube, but does it impart to any degree a metalic taste to the tobacco?
