double braid to 12 strand "Tail Splice"

[jeffh]

I've been playing around with some spare pieces of line and trying to tail splice some 12 strand HM line into STA-SET. Seems like a lot cheaper way to go than stripping cover off of some V-100 Endurabraid etc for halyards and lightweight sheets/guys. As there seems to be a lot of wasted core coiled up in the cockpit in the standard stripped cover procedure.
I've tested a few of my "experiments" with a chain hoist and they seem to hold pretty well I am, however ,concerned with shock loading that occurs with halyards and spinsheets when made up in this manner.
If anyone out there has any suggestions (or experience with) as to:
1. How far "in" should the tapered twelve strand be inserted into the core, to provide sufficient strength.
2. What sort of splicing "pattern" would be best while splicing the core and then the cover into the 12 strand (ie over one under two ? over two under one ? etc).
thanks for any feedback.
