Yeah, that's what I want, a big hunk of gyros meat, that I then slice, dice, chunk, and heat up to use in various recipes. Now of course a 15lb cone would be too much. This would be a kin to having say a whole pastrami, in terms of size.
If I went to a restaurant they'll be slicing it thin from a Kronos like cone right off of their rotisserie, which might dry it out.
