imo all points opens should be run as weighed. this would stop people looking for easy points, as if you needed points to say win the top ten with a 16 lb dog but you knew there was dogs you could not beat, but no dogs in the 40lb class. you could do a solo in that class and win the top ten,NOT VERY SPORTING AND NOT FAIR. (this is a an example to point out unfair it could be)
