I just discovered that there were other options for figure-eight mics for M/S and have found very little opinions on the blue line stuff from AKG.
For about $1300 you can have a cardiod condenser and a figure-eight pair for essentially half the cost (new anyways) of a mkh30/40 pair. Plus there would be new capsules to buy to add a shotgun or hyper.
I take it they are in the awkward mid-tier price range where people are usually gonna go for gold or go home kinda thing.
I've heard some concerns about noise but that's really about all I can find.
