Fearless or reckless? Thoughts on a push for all my chips

[arod15]

1-2NL live NYC
Effective stacks 700 Although hero covers.
Hero is MP picks up AJoff
Raises to 22 standard
Villian on the button cold calls
Villian is a lagish player with good postflop game
He respects me although he considers me a rock

Flop is A [img]/images/graemlins/spade.gif[/img]10 [img]/images/graemlins/spade.gif[/img]5 [img]/images/graemlins/spade.gif[/img] (pot 47)
I lead out for 35
Villian cold calls
Turn is a 2 [img]/images/graemlins/heart.gif[/img] (pot 117)
I lead out for 50 Villan raises me to 150 straight (317 pot)
I push. Thoughts? Is this reckless?
I was 90% he had no spade.
I also know he is likely to raise me with less than an Ace.
He had 400+ so it's def a tough call with anything but the nutz....
