High output MC cartridges


I'm looking to replace my MI cartridge with a HOMC cartridge.
I've narrowed it down (price/output mV) to either the Dynavector 20x2 MC, or, the Sumiko Blackbird MC .
Before I take another plung .... I thought I'd run it by the AG community to see if anybody out there has experience comparing these two offerings?

One of these days I’m going to take your advice and purchase a NOS unused Shure VN5xMR stylus. I’ve noticed more and more NOS and used Shure VN5xMR styli come onto the market within the last year. I’ve had the opportunity to purchase the rare Shure ULTRA but not the high price money to pay for it. 
@tyray yeah, NOS styli for rare tip top cartridges is a must have, only with NOS original styli we can actually hear the great potential of the best vintage MM. But some of them are very hard to find.
