I made the same transition to an aluminum boat several years ago. I bought a 17' tracker with a 70 hp motor. I really have not had any regrets and I fish the same waters that I fished with a fiberglass boat. The things you give up are ride and usually speed.You will gain towability, fuel savings easier loading/unloading etc. The only lake that has ever posed a problem is Kentucky Lake during high wind periods and that has been fairly rare.Bottom line: If your not fishing high dollar tournaments and are a weekend angler it is a good trade off.
