But if the pinch isn't tightened extremely firmly you are likely to get that "sinking feeling" sooner rather than later.
Ever frame I've ever had or played with the seat post is a light push fit or a slip fit but with no detectable rocking play. What you have at present would see me cutting up a pop/beer can to make a sleeve shim to fit between the post and the insert to remove any detectable rocking of the post.
Or.. head to a hardware store for a proper Shim material, cut and bend as needed, as i suggested a few dozen posts ago... sadly, people became too enthralled with protecting an overpriced seat post, and a titanium frame.... which was bought "new" then sat around for a long time for an undisclosed reason.
General message... have fun... go ream out Seat tube sleeves that are already oversized, as was suggested earlier.... i've got a Fox Float shock to clean thief paint off of... same color as my old Rally Car, actually, a lovely shade of blue.. i really miss that car.......later.
