Worth a call?

[BlackAces]

Early tournament hand...I've managed to triple up by this point, but there's one other at the table with my size stack:

PokerStars (9 handed) converter (http://www.selachian.com/tools/bisonconverter/hhconverter.cgi)

Preflop: Hero is CO with 8/images/graemlins/diamond.gif, 7/images/graemlins/club.gif, 5/images/graemlins/diamond.gif, 6/images/graemlins/spade.gif. SB posts a blind of 15.

Results in white below: <font color="#FFFFFF">
SB has Ad Qc Ah 9h (one pair, aces).
UTG has 4s 6d 6c 8s (three of a kind, sixes).
UTG+1 has Kc Jd Ts Qs (one pair, tens).</font>

I was planning to call until the big stack called. After that, I didn't want to get in a situation where he could push me off my hand on the flop, because he was being very aggressive.

Does anyone else call here?
