I bought a Lamson Litespeed 2, Series 1 with that finish on it in early fall. I mated it to my new Orvis Superfine Far and Fine. I'm sorry to say that I have NOT had it out yet but work, home duties and responsibilities have prevented any on-stream time.

It is a pretty finish, a grayish-tan.

If it is actually tougher than the old Guide finish, you won't have any problems. I have a Litespeed 2 on my XP and no scratches or problems to date ( but I'm careful and don't bang them around much )
