I've havn't yet had a chance to cast them at a fish, but I have had a cast with both of them just to see how they work.
The Crazy Dog is a floater... the Big Foot is a sinker. I've also found the Crazy Dog tends to dart around a little more than the Big Foot, but isn't quite as stable, as in, it does tend to blow out a bit if you dont get the action just right.
The Long Tom... I guess is not a lot different to other pencil popers. It casts a mile and is fairly easy to work.
IMHO, both are great lures from the Orion stable.
