The draw should be the same, like you I have a 27.5" draw
If your thinking of getting the monster, consider the harsher draw it has compared to the Z7. Also with that harsh draw, it will be harsher while sitting in your stand during the colder months.
I've been shooting MATHEWS for 14 years, my first one was the ZMAX, then the SWITCHBACK XT, now I have the Z7, all of them are great bows.
