Spinnaker “Bridle Measurements”

I am rebuilding my spin pole and wondering is there an “A” typical size or length of wires that should be used or rope. (Front to ring / ring to end) Same on Lift verses down-haul?
I also noticed some boats running the down-haul from just forward of the deck hatch and some to the mast base. It seems to be an advantage to have it running to the mast but I also see a lot of downward force not distributed evenly. I am in the Gulf Coast area with the exception of this spring our typical winds are 5 to 10 and 10 to 15.
Dale,
We have about three feet of space between the bridle ring to the pole and use 3/16 Dyneema. We sail in heavy air a lot so our fore guy is split and is just forward and outside the hatch. I plan on making them movable to the mast base as well.My downhaul is at the mast base…keeps jib sheets clear that way. BUT, we use twings to supplement the downforce. Couple of years ago we went to a carbon pole and use ‘center pick’ D rings. VERY nice alternative if you have ever considered it. Forte is the only one I know of that does the center rings on carbon poles.
Is there an advantage of stability of having a center-point of support for the pole D ring as the Forte. I guess that could be a question for Forte but would like to hear about your experience with both pole types.
Thanks
DaleCenter point: advantages are small, but add up. Don’t have to deal with bridles..clumsy at times. Pole ‘spins’ easier during gybes. The pole lift and downhaul are directly opposed to offset each other. Carbon is super strong and very light..a one arm easy lift. D Rings don’t break.
Stability? probably the same when hooked up. When the pole is at the forestay, the end of the pole bends up and down a bit in waves..but Forte says it won’t break! Don’t forget they build the sprits for Melges 24’s and the like.
Whats you opinion of converting an aluminum pole to this configuration?
How much does it flex at the tip? I would be concerned with the flex on a power reach on the edge…
Aluminum would fold like a bent straw…don’t even think about it!!
The carbon can take it. The flex at the tip is less than the flex on sprit boats..only flexing from mid point out..so 6′.Thanks everyone for your comments and opinion/s this will help a lot.
This is a great device! I found some more information on this website: http://www.nauticexpo.com/boat-manufacturer/spinnaker-23326.html
