Zuzu, have you decided which OGRs you'll be using? I've gone back and forth on this too. Japanese beetles have been more problematic here the last couple of years, which has me thinking I should try more OGRs. Since they bloom before the beetles emerge, they put on a great show without problems.
As for own root verses grafted, I'm finding it dependent on the variety and a matter of trial and error. Thankfully the own root plants I got from Chamblee's this spring are all performing quite well, a couple are even close to catching up to the grafted plants in size.
