I got a Willie because I know for me the benefits of aluminium outweigh the plusses of 'glass. One thing I have learned about major purchases is to get the best you can with all the options you want so you don't end up dissatisfied in the long run for saving a few bucks. Whether you go with aluminium or glass, purchase from an industry leader and you won't regret your decision. Quality holds its value. Hope to see you on the water.
