I've had a chance to compare some of them to Lundahl and OEP in a similar situation (more specifically the NYD two-bottle, and one-bottle, which require about 1:5 to 1:10 ratios), and I wish I could afford them always.
I'll do a MILA-1 this summer with cinemags, to get some experience with them.
Remember that in some other topology the sound will change, and my example is a very narrow one (and even then only my personal preference).
