yeah I 100% agree with you here.
SPR should not be the first thing that comes into your mind when you see a flop.
Edit:
<m2m> i think its something we already think about anyway
<m2m> big pot relative to stacks = easier to get all in with 1 pair
<m2m> small pot relative to stacks = need pot control etc with weaker hands
we already intuitively think about spr, so it's time to look beyond a simple ratio and think outside the box a bit.
