I have a Kieffer Pear and a Seckel Pear. The Kieffer gets bad FB just about every year. The tree looks terrible right now, probably going to cut it down this year. The Seckel, on the other hand, is only 20 feet from the Kieffer, was planted the same day in 2007, and has never had the first hint of FB at all. So, maybe you should try a Seckel. Seckel pears are small, but if you let them get just slightly soft, they are oh so deliciously sweet.
