What do I mount my Guardians on?

Trying to get into touring and I got a really good deal on guardians on ebay. The problem is that the only skis I have are very beat up 178 chronics and pretty new 194 4frnt devastators. I realize that neither of these are ideal but I don't really have money to get another pair of skis. Afraid the chronics won't hold up in deeper snow and obviously the devastators are going to be heavy.
