Dux Rigging - Turnbuckles and or deadeyes

[alaskanviking]

I recently called Colligo Marine, requesting advice on thier chainplate distributers. i wanted to ensure my new plates would fit them. they told me that they have found that on the bigger boats the deadeyes do not give enough pretension, and therefore they reccomend turnbuckles. this makes sense but i do like the new/old look and the simplicity that deadeyes provide. i was wondering if i could get enough pretension using turnbuckles for the cap and intermediate shrouds but use deadeyes for the fwd/aft lower shrouds, and Checkstay (cutter rig, but not sure if that is the right term).

Thanks
