doel fins. our experience has been a very slight drop in wot.
slight increase in fuel economy. cruise speed down by perhaps 1/2 knot
or so. .but the ride was improved greatly. less of the side to side
motion GBs are known for . and yes in a following sea a better ride.
overall it is a positive for us. im sure others have their own opinions.
as far as how they look. come on guys. we bought our cat nearly 6 years
ago when cats REALLY werent cool. so that is a non issue for us.
