I have given up on the larks head and would not recommend it as it has failed twice for me. Summer winds around here are in the upper 20's to low 30's most every afternoon so jib sheets get heavily loaded. Using 7/16 Vizzion I find the good old bowline knots are more reliable. Tie one enough longer than the other to keep them from "doubling up" as they round shrouds or baby stays. The other advantage is you can end for end the sheets when the knot end starts to chafe.
