I went HIF.

They are more complex, and possibly more expensive, but they work  
pretty well once you get everything set up.

The true PITA (and I have experienced this) is that because the float  
bowl is integral, you can't open it up without a lot of work.  I had  
a chunk of dirt in the fuel needle which caused my carbs to flood.   
Cleaning that out would have been trivial on the HS4.  As long as you  
don't plug in a dirty fuel filter backwards, you should be ok.

My conversion is not very well documented here:
