[Santana 22] Replacement Tuna rigging - Dyform or compacted wire, anyone?

Fellow Tuners,
In a nasty blast a few weeks ago on the Bay, Carlos' mast suddenly went 
sideways, outers parted at the top and inner at the bottom.  Amazingly 
mast is fine (and so are all the crew). So I need to replace Carlos' 
standing rigging, and someone suggested Dyform or "compacted strand" 
wire.  They are both SS wire but pack a bit more steel into the same 
diameter (I think) and are therefore somewhat stronger and less stretchy.

Does anyone have experience with either of these - or know whether they 
are legal, for that matter?  For reference, this is what I see in the 
current rules (first entry is in main body, second entry is in checklist):

14.Wire rigging shall be of the same dimensions and materials as 
supplied by factory except as to lower shrouds.Turnbuckles must be not 
less than factory specifications as to dimensions and materials.No rod 
rigging is permitted.It is suggested that boats sailing in heavy air 
replace the factory supplied 5/32” lower shrouds with 3/16” wire.

B.Standing Rigging

1.All rigging is 5/32” SS wire. Lower shrouds 3/16” max. No rod rigging


Thanks much,
Jan Grygier
