My VPIP at the X-Party skins has dropped

At 1/2 it's normally around 16, but since party ditched them it's dropped under 14. The tables are so TAG that I can't open limp anything cuz I'll get raised 80% of the time and I have to fold my SB a lot. I'm stealing more (40%) and defending my BB more (fold 55%) to make up for it somewhat, but not enough.
Is this VPIP too low for these tables and what hands can I play to increase it?
