Flat edge

[Paul Goodwin - US 46]

I don't think you ever told us your weight? 

Anyway, since you have only one set of 36" insert runners, the answer is very simple in my opinion.  Sharpen them at 90 degrees, 18" crown, no true flat.  That is how I try to tune my long inserts.

Bob Gray mentioned talking to Matt Struble about runners.  Here is a another tidbit - Matt used his 3/16" inserts with 18" crown in every regatta one year, and took 1st place in every event including the North Americans.  Another tidbit from that NA - Matt did not adjust his rigging, while the wind went from 12mph to 20mph.

Takeaway...  get one really good set of long inserts, tune them to perfection, use them all the time.  Learn to sail your boat rather than stress over the "runner of the day".
