We all have OD specs no modifications and each have a 150% and a 110% head sail with a .50 spinnaker. The only difference from mine is they both have roller furlers and I have a track that has two slots to do a sail change underway.
Post links to the certificates to see how PHRF New England rates them. This is actually a question for your PHRF rating committee which they should be able to answer with certainty based on the data, or adjust the rating.
