Help with short scale strings

[fox]

I have a tenor guitar with a 20" scale but I find the on line string calculators a bit tricky to use!
Can anyone work out for me what gauges & type would be worth trying in CGDA please.

D'Addario J66's, Scale length 23"
A4 .010" PL == 23.5#
D4 .014" PL == 20.52#
G3 .022" PB == 20.79#
C3 .032" PB == 19.71#


Custom gauges, Scale length 20"
A4 .011" PL == 21.5#
D4 .016" PL == 20.27#
G3 .026" PB == 21.72#
C3 .036" PB == 19.02#
