how do you play this table?

i have a table texture of:

on my right...maniac.
2 off my right...maniac.
on my left...rock. less than 10% vpip.
2 off my left...call station. 70% vpip, 1% pfr, and 60% to showdown.
3 off my left...tight/passive.

how can i isolate the maniacs w/ the caller in position on me most of the time? does this make my seat hard to profit from?

or do i just find another table?

i worked awfully hard to find THIS seat and the caller came in and wrecked it. if it weren't for him, this would be a dream.
