I've had most of Hayden's pickups, but I have given all of them away! I liked them through Matamps, but when I compared them to BK's I realised that there wasn't the depth of sound that Tim gets. I have other pickups (even some old SD's), but keep coming back to BK's. I have quite a few custom BK's, but I've known Tim a long time and have all the BK range practically (some several times). I'm not sure how Bulldogs compare price wise, but Hayden will make you custom pickups, if that's what you want. Just out of curiosity, what type of pickup are you wanting?
