A few toggle design choices

[paramita]

Hello All, in preparations for re-rigging my boat (1984 Ericson 38) I have most of a complete schedule of materials put together. As this is my first attempt at anything of this nature, I will be working with a local rigger to help minimize first time/amateur mistakes. However I have a few questions I want to run past this audience so I can be confident in my own design choices. Basically I'm looking for input on various toggle choices.

1) I understand ideal practice is to install toggles at the mast connections for all shrouds. Is this still advantageous if my shrouds are connected to the mast with a T-Ball connection?

2) On the topic of the mechanical T-Ball connection; From searching this forum it appears the Hayn fittings have the best breaking strength spec. Based on that information I was planning on using all Hayn connections, except for the T-Ball mechanical fitting which is only offered by Navtec. Am I wasting money on Hayn fittings since there will be a non-Hayn (potentially weak-link) fitting in the same path? Just looking for some thoughts/opinions on this one.

3) My stays are currently connected to the masthead with an eye-jaw toggle strap. Is there any pro/con to sticking with the eye-jaw toggle strap as opposed to something like this eye-jaw toggle (TOG10 http://www.hayn.com/marine/rigging/tj.html) there.

4) Per the recommendation in The Riggers Apprentice I intend to toggle the top and bottom of the shroud turnbuckles. In this case I'm wondering if there is an advantage to either of the following combinations for the top part of the turnbuckle. They seem like they would function identically to me but there's always more to these things than I usually think.

opt 1: wire->compression toggle -> Turnbuckle w/ RH Eyebolt top...
vs.
opt 2: wire->compression eye ->Turnbuckle w/standard upper jaw top...

Thanks in advance for your input.

Mat.
