Small Pairs <66 v reraise

[xPeru]

General advice please.

First to speak with 55 or lower pair, I open 4BB. Btn min raises to 8BB, BB reraises to 12BB.

What stack sizes do you need to see to call? What reads do you need to call/shove?

Sry not to be more specific, but I'm currently folding here 100% and I think it's a leak.
