Which List?

By riddlesworth, in X-Wing

I'm contemplating 2 lists at the moment. Either a stock XYBX that i've run for the last 2 weeks, or using the Chardaan Refit to swap an xwing for an A - less brawling, more flanking.

Squad 1:

Garven Dreis

Dutch Vander - Ion cannon

Blue Squad - advanced sensors

Rookie X wing

Squad 2

Garven Dreis

Dutch Vander - Ion cannon

Dagger squad - FCS
Green squad - refit, push the limit
the first squad has more brawling power (more attack dice, more hull), but the sexond squad gets more actions. I'm more likely to get TL/F off (the a-wing can do it on its own, and FCS keeps the B-wing on the tail of whoever).
I know advanced sensors is the bomb on B-Wings, but i'm wondering if i might get more utility out of the faster A?
