OK thanks for all the input guys.. I'll get a copy of the STS article.
Bob its sounds like if the bowmount power steer motor (mounted on the transom or stern) is not much use for holding a straight line while pulling plugs and you prefer your transom mount 55T for drifting eggs I'm not hearing a big reason to invest the extra money in a bow mount (power steer) motor. I'm curious when the power steer feature does come in handy ... trolling plugs for coho in soft water? If I do end up with a bowmount minn Kota, I'd be curious to see your bracket design.
