The S65 is a very nice post, like most Nitto products, and will work great for you if it's the correct length and diameter for your frame.
I've got the Ritchey Logic version of that post (made by Nitto) and it's great. Will not slip. The interface between the clamp and post is as good as a Campagnolo Record.
