Class rules allow a #1 genoa with an LP of 13' 5" to 13' 11". This corresponds to a sail that is between 150% and 155%. My guess is that most folks would order the 155% since it is allowed.

If you cannot sheet tightly enough with your jib lead arrangement, then the clew of your genoa can be adjusted by your sail maker...
