The new flange kits are definitely the fix for those things. On smaller ones with 4 bolts, I've had some success drilling and tapping the additional 4 holes. Even on the 8 bolt and 12 flanges, if you are meticulous with your installation and pay attention to the details, they're not problems anymore.
