Shane,
My last cheddar, which was very, very good (and still is -- though it is disappearing fast!), had approximately 3 gallons of milk (actually, 2 gal whole, 1 gal 2%, and 1 pint cream) and used 3/16 tsp MA011 (same as the MA16 you have) plus 1/8 tsp TA061. I didn't have any MD88 at the time; if I had, I would have put a bit of that in as well.
Since FD has the same bacterias as MA011 and MD88, plus one more, I'd be tempted to try FD + TA. I say that, but in fact I've never used FD, and from time to time I've heard that it might be a bit slower in acidifying ... ?
I like Spoons' suggestion of some LH ... may have to try that this weekend, when I am planning on making another cheddar ....
