Hello Fright, (interesting handle)
I hope you don't mind my chiming in here but as I have been closely following both Arnie and Evans builds for quite a while I might offer a suggestion.
I know Evan is using a lot of white metal fittings from Bluejacket and he, I believe Arnie, as well as myself, purchased Bluejackets plans for the ship. If you go to this link http://www.bluejacketinc.com/kits/ussconstitution.htm and click on the parts list, it will bring up a pdf that will break down all the blocks and numbers needed as well as rope sizes they use for their wooden kit. I am rigging my Connie based on their plans.
Arnie used the superb and I mean SUPERB Boxwood blocks as well as cordage from http://www.syrenshipmodelcompany.com and I think also from http://cottageindustrymodels.com/ . I am amazed at the quality of the blocks and cordage from Syren, and I am following Evans method of using white metal from bluejacket for the deadeyes but I will be using Syrens blocks everywhere else, Arnie used Syren throughout his excellent build.
A word of caution here, you mentioned this is your first attempt at a full rigged sailing ship, in no way would I discourage you from the attempt. That said, as we have had this discussion elsewhere on this thread with another modeler jumping into the deep end of the pool, this kit is not for the faint of heart, I have built 4 1/96 scale Revell ships and I am nowhere near as skilled as what Evan is doing, Professor Tilley pointed out, correctly I think, that he believes only a small pecentage of these big kits ever get finished. I am nearly 2 years into mine

and have yet to mount a mast, and have spent more time on the channels and boats than I even thought possible.
I guess what I'm saying is go for it, but be patient, patient, patient. The tedium in some parts of the build can discourage anyone, when that happens, break it into smaller increments, mini models as it were, like the way I'm building the boats as seperate models. When some part becomes mind numbingly tedious, like rigging the guns, stop, work on something else for a while. If you do indulge, keep a good single malt Scotch on hand and realize this is no quick and easy build, but the end result is so worth it!
