Slim,
If your 175 is getting hung up, you need to resolve this problem. The only 
place that it could hang is on the shrouds. A good and properly sized shroud 
cover will take care of this and I'm not talking about the thin wrap around 
plastic covers.
Take a look at the pictures of my rigging and you'll see that I have large 
PVC covers that act as large rollers. I never have any hang problems, even in 
lite air.....the sail goes through with little effort.
Another problem I've seen is that some owners actually have to two separate 
lines going to the clew instead of one line with a knot. Two lines, two knots 
makes for a problem and something else to hang up..Rhodes Rigging
