I go out in a couple of boats mostly off shore, one FG 6metres long, the other is a 6 metre crusher, both are running 150 yammys, the crusher leaves it for dead and uses half the fuel but the owner of the glass boat wouldnt have it any other way as he prefers the ride, i think a big part of it is the type of fishing, we do a lot of drift fishing with a sea anchor , not much trolling so prefer ally but maybe with trolling glass would be more comfortable. bottom line, endless debate that will only confuse you more
