what size short broadhead adapters do I need for ce150s, the point size for them is 5\\16, but I want to shoot 11\\32 broadheads, is it possible to shoot 11\\32 heads out of a ce150?
Yes, but the arrow will be more difficult to remove from a target. And easier to lose your points when removing them from the target.

No problems at all. It's all I use with steel screw in adapters. Never had one pull out and I use hot melt for all connections.
I strongly suggest GoatTuff for your glue.
