Dave,
I am unfamiliar with the mighty might. The riser and geometry are a bit diff. so I don' t know if you will achieve center shot with the shakey. Noe do I know if there will be a problem with nock travel.
If you read my (steam letting post) I believe I posted some pretty good instructions from TT and Bowtech for setup.
I will look back and repost them here
Good Luck
