I have a JMI attached to my SCT and I'm not too impressed with the 2" compression ring. It doesn't hold my ST 7 orthogonal to the scope, there is always a little bit of sag which shows up as out of focus stars in my dec axis. I can't say if it would be the same for a reflector but it is something to be aware of.
