All of the 3rd party 2007 Primes I know of are based on MPM-4. But the only ones I know about are the WJ, BmB, and LT. So is it the MPM-4 design that's the problem, or just some aspect of that particular rendition?
The Black Apple "KO" of MPM 4 is so different from the source material that I don't even consider it to be MPM 4 anymore. Give that one a look. It's spectacular.
