I've tried both, but have generally reverted to charging on a wider front with close formation.

Yeah, it's +3 attack -3 defense so there isn't any advantage to using it in a head on charge. With a wider front on the other hand you get a better charge bonus. If I have time, I've used it it with ya, ys, and sa when attacking another unit from the rear as the unit doesn't defend itself for a little while. Usually not worth the bother though.
