75$ 6-handed mtt: too tricky for my own good?

[memento_mori]

Villian seems to have played very decent so far, very small sample though.
The flop was pretty dry so I decided to lead out, esp since CO had been limping way too many hands. When the button raises my std line on such a dry flop would be too fold.
However I have a hard time putting villian on any of the hand he represents.
I think that 99+ would reraise preflop to isolate against co, 55 is unlikely (although possible) as I hold one of the 5's. 22 is a serious threat, and fits his line pretty decent so far, although slowplaying on such a dry texture would prolly be the standardline.
Shoving - sexy or spewy?
