Well, I was curios to see how old both the cams were and the 150 is older than the GL2.. both are rather old models (Gl2-7, 150-10)
Even still, I used to have a GL2 and currently have a 150 and I wish I would've never have wasted my money on the GL2.. not that it wasn't a good cam but just because I love my 150 that much more.
