Pete,
there are many ways of making a split tail without splicing. Be creative and get a large needle+sailmakers glove. If nothing else, stitching the tail to the traveller line will do the trick, even if it is a but crude. Pulling the cover of the control line back, then stitching the tail on in different ways is also feasible. Think a bit ahead then Get To It

Did you see the gusts coming? Instead of coming up in short blasts, how about sheeting a bit out and sailing through them with greater speed? Depends on conditions of course.
