Only word of caution is that Nicopress fittings are specified
for aircraft cable.  I once asked the company about using them
on 1x7 EHS guy strand and they said they would have to do
some testing.  This was 20 years ago and I haven't seen the
test results they sent me in many years, but the results
basically indicated that 1 fitting was never enough to meet
the tensile strength of the EHS.  Two fittings usually were enough
but not always, and that it took 3 Nicopress fittings to guarantee
that the EHS would fail before the fittings did.
