Adam is not the only breeder to make that statement. Ralph and Kevin both have, that I know of, and multiple other breeders have all stated that they believe that ALL spiders have a degree of wobble to them - from just barely noticeable to full out spinners.
It is becoming more "accepted" knowledge that all spiders have this to some degree. Even VPI is rating theirs.
I personally don't think the wobble is a bad thing - it seems those most offended with statements that all spiders spin are those that seem to be worried the most about some negative stigma associated with them.
The more people acknowledge that it's just part of being a spider, the less "taboo" it will be.
