With the MMF-5, go with whatever is cheap and sounds best for you. Don't try to spend too much money tweaking the Music Hall (this is coming from a former Music Hall MMF-5 owner). I'd bet the cork will sound better.
You'd probably be better off 1) downloading an arc protractor and verify the alignment is spot-on, and 2) getting it directly off of that glass shelf and on to a maple cutting board (painted black). Both will be useful if / when you upgrade.
