I need a good cherry (or two, if not self-fertile)

I wanted to grow rainier and bing, but heard that was not a good combination in nj because of wet springtimes.

so which varieties are good? sweet only, please. :)

i'm in cumberland county which has 7a status. Which I think is just a bit warmer than the rest of NJ.

thanks.

oh and any pointers would be great too!!
