Bubble situation

[11t]

Was wondering if anybody folded here, I had been bullying the table (standard bubble play) and the button had made several comments about it. I would assume a range of roughly 22+, a5+, j9+, q8+, k7+.

Now my question really isn't what is mathematically correct, I know that calling here is +EV, but I know several people advocate preserving the bubble so that you can wield your big stack and win first before you get HU (more or less). Also if I call and lose I will lose my big stack status and the blinds are raising again.
