heavier gauge on Six, any suggestion?

[marcopalla]

Hi,
I usually use d'addario EPS170-6 ProSteels 30-130 Long Scale 6-Str
that on box have written "regular light"

so now I'd like something heavier to get a lower action,
BUT d'addario seems to do only that gauge for six:

is it right? not "regular medium gauge" for 6?

what else can I look for: stiff and bright ??
and little heavier than
.030 .045 .065 .080 .100 .130

thank U very much!
