There's been a recent spate of threads dealing with the TF89 in the airgun gate, it shouldn't be too hard to find info on it. Personally I have a B28A but am also a fan of the TF89. If you've never had a magnum springer, I'd go with the TF89, it's just more refined in its firing behavior. And it's not like it's lacking power at all, a lot of people have them shooting at about 20 to 21 fpe, and that's nothin to sneeze at!
