That's idiotic, or at least short sighted.
Use the biggest pin shackle that will fit in the torque arm, and 1/4"
big grips (preforms) with thimble in the shackle. This makes it easy to
remove a guy wire temporarily whenever needed.
As has been pointed out often, the torque arms don't do much for
rotational resistance, but if you have them, use them. It makes a nice
install.

I acquired some used Rohn 45G in very good shape and will be going up
50 ft. Antenna will be stacked 2 x 9-el for 2m. I'm following the Rohn
engineering guidance very closely: base is a new R-SB45G buried in the
prescribed concrete block along with GAR30 guy anchors, also in
concrete. I have the older style guy bracket for 45G that has (very
expensive!) TB45D torque bars

along with several hundred feet of brand-new 1/4 in EHS for the guys.
According to the Rohn instructions, however, I can't use EHS cable
that's greater than 3/16 in:

This means I'd have to buy either smaller EHS cable or their newer guy
bracket that doesn't use torque bars. I'll do this if I have to, but
I'd sure like to understand why 1/4 in EHS is a deal-breaker for the
torque bars. QTH is north Florida so I want to make the setup as
storm-proof as practical. Any insight appreciated.
