Interesting study done about 5 years ago regarding bucked shins.
http://www2.vet.upenn.edu/labs/corl/...uckedshins.pdf
I would gather racing 2 year olds on dirt surfaces isnt beneficial, in relation to bucked shins. Part might be from the development point of a 2 year old, part may be the surface, and part may be the speed of the horse in training.
Bafferts style, with his QH background might lead to the approach he has shown with T-Breds and 2 year olds, and thus the expected results.
There is a ton of techincal stuff in the article and some general stuff you can conclude from the findings.
Perhaps it would give all on this topic a clearer idea of bucked shins.
The article is about 14 pages and in pdf format.
Just a side note. Calling a poster a clown, or other names serves no purpose.
Ignore the poster, argue the points of the argument, but name calling is not what a forum should be about.
