Hi Greg:
     If you change to the rings etc. you will no longer  have a one 
design boat, and knowing what most traditional sailors know about 
sailing, they will find the rings more difficult to sail with than an 
adjustable track car. That system does not allow for easy sail 
adjustment short of either changing ring position if you have a snap 
shackle attachment or rethreading the sheet, for changing wind speeds, 
especially  if you need to either really bag the sail in lighter air or 
really flatten it in heavy air or adjust the car for a spinnaker or 
blooper twinge control line. However, teh controls and sheet placement 
on that class of boat as you describe it makes for a one design class as 
long as no one installs reacks!
     If you watched any of the America's Cup, the sail adjustment was 
infinite but by millimeters and all on tracks or the equivalent. You 
cannot do that with the rings. The adjustment is from padeye to padeye. 
Sometimes, newer ideas are not any better than the tried and true.
     But, there is nothing wrong or bad about dynema for sheets, except 
if your winches wear the lines, then it is expensive.
     If you do go to the rings, keep the tracks for the next owner 
because he will probably want them for two reasons: it will still be a 
class one design boat and they are easier to adjust a finer sail set 
quickly, especially for racing.
