Hey Jake,
You can help me here. (either via the forum or in private)
I don't have much data on these singlehanders and I'll need that in order to tweak the single handers. You as a F18 sailors may help us out here.
How often have you sailed against these singlehanders and how did they compare to your F18 ?
I'm particulary interested in the I-17R as that is such a clear example and I can cross reference it with I-17 data. These are great setups; Identical setups with only a small of differences. Makes for great tweak keys.
Wouter
