Good move?

[Nightmare Fuel]

10 person sng, payouts 30-18-12 (peanuts to most, i know)

down to final 4, blinds 200/400

big stack - 9.5k
guy a - 1k
guy b - 2k
me - 2.5k



big stack in 1stp pushes allin (as he has been doing quite frequently shorthanded, without much resistance), guy a folds, guy b folds in sb, comes to me in bb with pkt 66. he previously had to show down his hand once (jts)when guy b doubled up off him. despite the big stack having so many chips, i don't really think all too highly of his play, and am pretty confident in my chances of beating him if i get to heads up with at least half his chips (the more the better).

long story short, i was almost certain i wasn't up against a better pkt pair and most likely just 2 overcards, and decided to call instead of playing for 2nd/3rd. he showed down a5o, my 66 held up, and i doubled to nearly 5.5k. within 10 minutes after, i had indeed won it all. but was it the right move if played the same over the long run? thoughts?
