Thanks for all the replies! At least I feel confident now that I made the bridles to spec on my 6th Sense. So for future reference ....which bridle leg on a typical 3-point bridle configuration does the term "incidence" refer to? Is that the upper outhaul leg? Same question for "external" and "discharge" as another builder referred to his bridle specs? IT's not at issue for me now but just for general knowledge, I'd like to know!
Comon terms for bridle legs are as follows(letters refer to IAns other diagram):
(A)Up haul/upper out haul = towpoint to upper spreader attachment point
(B)Out haul/lower out haul = tow point to lower spreader attachment point
(C)in Haul= tow point to spine/center T attachment point
(D)Turbo leg = in haul attachment point to out haul attachment point of the tow point pig tail (usually the prussic knot on the outhauls to a knot where the inhaul is larks headed to the tow point pig tail)
(E) Tow point pig tail

Regardless of the letters used the orientation of the legs is what you need to know. Some languages don't have a direct translation to english so the terms may not be right. As for the terms you mention I would assume "incidence"=inhaul "external"= outhaul "discharge"=UPhaul but without linking to the plans you got those from its hard to say for sure.
