Any horse can run barrels, especially at the local level. A lot of the top-flight barrel horse lines carry quite a bit of TB blood, and quite a few well-known barrel horse sires are TB or half TB. At the true upper levels, a pure TB is generally not going to do as well, simply because when the money comes down to 1/1000 of a second, the tighter turns and fast acceleration of the QH can make all the difference.
But yeah, locally, there are quite a few gals riding OTTB's or TB crosses and doing pretty well. Resale is not as high, but if you want a TB and find one you like, it's worth doing. You want a good shoulder, good legs and good hooves and a stockier-built TB. If he looks like he just won the 5th race at Belmont, stands 17.2 hh and resembles a greyhound, he likely won't do as well as the ones that are a bit smaller, less 'rangy' and could pass as a QH if you didn't look too close.
