Cinta, The Pacific series and all semps should be fine in PA. There's a few tender ones out there, mainly things with lots of hair and species from Turkey and Iran.
Almost all of Gary's look to be within the basic European complex (tectorum, montanum and arachnoideum). These are your best bets for hardiness.
Unfortunately unscrupulous nurseries might be labeling them "Pacific" but they aren't really! Ordering frrom reputable dealers will get you much further!
