Also in PA and growing lots of varieties for the past two years, I've seen a lot of leaf roll and it seems to bother some varieties more than others even though all get the same treatment. Often the leaves just stayed that way for the season- usually the lower ones. It doesn't seem to interfere with fruit production. There are so many possible causes that it's diffucult to pinpoint the problem so I would just ignore it if it's not leaf curl.
Flea beetles are very common here, too, and usually just affect the bottom leaves. They don't transmit any disease I know of so I don't spray for them- but I squish the slower, distracted ones.
