I broke the handle neck on my non-bailed 150, so to make do I unscrewed the bailed-150's handle assembly and used that. The bailed 150 has a longer handle neck and I liked the feel of that one better, so I ordered that one to replace the one I broke. Problem is, the handle hubs are different on the two reels and the longer neck wouldn't seat correctly, so I kept the handle hub on the non-bailed 150 and just switched handle knobs (I like the little one better).
So, there you have it.
Not sure if anyone else has this issue, but the non-bailed 150's handle neck is so short that it sometimes feels awkward when setting the hook. I also do something weird by reflex when setting the hook -- I put a lot of pressure on the handle neck with the mechanics of my hook set -- this is the second handle neck I've broken when setting the hook (the other was a VS275!)
