I'm sorry if I'm sounding anal about this topic, but I sail on a broad  reach 
frequently and have never found my current rigging to be lacking anything  as 
far as adjustment or the possibilities for sail adjustment for optimum  
performance.
I know that many people complain about the 175, but I find it highly  
adjustable and not lacking in most wind conditions. Perhaps my lack of knowledge  
with a lot of other equipment is hindering my understanding of this subject.  
That being said, I can tune my rigging for almost any conditions and do it  
easily by myself. Based on how my boat is equipped, it still sounds like trying  to 
reinvent the wheel.
