A couple things to consider:
MLF likely will not have any visible signs.

I tend to mail-order my VP41 bacteria and have found it very reliable.

If you are able, some grapes would be a beneficial addition, even in a small amount. You could split a grape pack between your batches to get some nice tannins. http://www.juicegrape.com/Mosti-Mondiale-All-Grape-Pack/ I add this to my red juice buckets for body.
WOW!! Fred's Meritage is really good. Like the complexity, acidity, oak flavors, dryness, firm tannins, full body, lovely dark color, and nice legs. Finish is tough because its both fruity and spicy. Nose is complex and the wine is nicely balanced.
