I'm a big fan of freehubs and cassettes. I've broken or bent too many axles on FW hubs. And don't get me started about removing freewheels on tandems.

With conventional 10mm axles, 7 speeds seems to be the practical limit in most applications. More makes the unsupported length of the axle too long

But for some HPV situations, in my case I'm looking at a delta drivetrain, the new crop of freewheels from SunRace and DNP has potential. You can even get an 11-36 10 speed from SunRace.  The DNP Epoch FWs look quite nice.  In some cases the cog selections make more sense than Shimano's cassettes.

DNPs 11-34 is odd, but maybe brilliant. 
11,13,15,17,18,19,21,24,28,34 they just dropped an 18 into the middle of their 9 speed. giving a wide range, but with ultra close ratios right where I do most of my riding.  

I can't imagine many people wanting these, but QBP has them in significant numbers.
