HM End to end splice

[RoyB]

I've searched high and low for a good end to end splice for Dyneema double braid but all I can find is splices for polyester or other non HM lines. I've got several of Brions books and tapes but I can't find the info in them either.

I need to splice our mainsheet together so as to be continuous and the splice can't be very fat as it will have to pass through some blocks from time to time. The mainsheet gets pretty heavily loaded at times so I don't think I want to trust the jacket, even if doubled in the splice.

What's the best way to do this splice.
