If you want someone that knows how to work a WGSL then you picked the right person. A few years back my SchH trainer and I watched two of Heidi's dogs in bitework and he (a working line person) was impressed. I've only met Heidi once but have huge respect for her, whatever "type" she's breeding, because she really knows her stuff and trains and titles dogs herself. As far as I know she's very well respected among the show and Schutzhund community.
