Graham ,
I got rid of the cheek blocks 18 years ago. They didn't serve any useful
function. I go directly from the genoa car to either the primary or secondary
winches. The lead angles are almost the same, and they're quite good, even
with the genoa car full forward for the #3 jib.
Midnight
I race with a 105, and cruise with a 135. With the 105, I run my sheets
through a fairlead a short distance aft of the shrouds, then through a
fairlead further aft, through a turning block and then to the forward
winch. With the 135, I run the sheets the same way but eliminate the
forward fairlead.
