Dan,
If you are going to be sailing on an inland lake, I would recommend the  175. 
Lake sailors don't have the benefit of constant winds like ocean sailors  
often do. The ability to furl and move the lines inside the shrouds makes it a  
good choice. 
I don't have the problem with the sail collapsing and I don't experience  
pointing or some of the other problems people associate with the 175. It's all  
about experience, knowing the boat and trying different things to find good 
sail  shape for the wind conditions. Balance is also important to sail shape. 
Often,  my crew members get annoyed with my constantly moving their weight around 
to  keep good balance, but that's why they are there in the first place. Oh, 
and  they also come in handy for keeping the drinks filled.
