Thanks for all of the great input! It was very helpful!
Stefan - I currently have the ET-73, but will definitely upgrade to the 732 at some point, so it's good to know about how they fit. Thanks for the pic and links too!
Travis - very cost effective!
r b - great idea about boring out the hole a little more...never really crossed my mind.
I'll be sure to post pics of what I end up doing.
Thanks guys!
