New wax comming

Ran in to Jim at the nordic center today.. Jim is what i hope to be when I am 64. Anyway we talked skiing and about the kids and he offered to wax up my skis , said it will make me go faster. The ski today was good fell like I am gettimg better with what my body needs to be doing. It was quite out on the trails and you don't see a lot of people, not may chances to ski backwards or jump on rails to tell you the truth the park is not like the one on mountian.......Do they make twin tip xc skis?
