For me, it really depends on what kind of conditions you'll be fishing in. I had an 18' SeaArk with a 115 on it and for fair weather fishing, it was almost perfect. It was wide, stable, up on plane almost instantly, drafted shallow, and sipped gas. But…..as soon as the wind got up above a puff, it was like a sail, and it was a royal pain. That was the biggest, and really only, complaint I had for that boat. I had to constantly stay on the trolling motor to fish, the wind just blew it all over. As for running, it handled regular wakes and chop just fine. Anything above that, and it was pretty rough though. When my boys got into fishing high school tournaments, I sold it and bought an older, but well maintained Triton 20X. Going to a bigger glass boat simply let us enjoy more days on the water. We no longer had to put it on the trailer when the water got a little rough, or even choose to stay at home when there was wind in the forecast. All that said, if you fish smaller lakes or go mostly when it's nice weather, aluminum will be just fine. Probably even great. But if you plan to fish the Tennessee River lakes where stiff winds blowing against a heavy current can create 3' rollers, I'd definitely go with glass.
