Haha yep most wb's are just big boof heads. Hence "dumb bloods"

As ridergirl said, the ones that crack it tend to be the ones that are stuck in stables/small yards, pumped with heavy feeds and only brought out to be ridden. Plus there are a lot that are being bred at the moment that have quite a strong tb influence that tend to be a little hotter. But as a whole, wb's are a pretty laid back mob
