Two Stop-N-Go hands -- one good, one questionable

[jcm4ccc]

I've been using the stop and go for the last couple of days, after reading about it on these forums. The first hand below worked very well (though some may think I should have folded). The second hand, well, perhaps this wasn't the place to use the stop and go. I don't know. Comments appreciated.

It seems to me that by far the most likely hands to reraise a 3XBB bet are in order AK, AQ, KK, AA, QQ, JJ, or 1010.
Now I'll agree that even KK calling an All in of a preflop raiser is pretty balsy. But if you are going to push the flop anyhow why not reraise all-in, preflop?
