I have the 9" Slammer and I just got it out and threw it the other day and it dives about 2' on a super slow retrieve. To say the least I was very dissapointed in it for not staying on top. I'm gonna try and get another one cause I know the Slammer is deadly on top. I would consider keeping it if I had the same success as the others with it subsurface. I have a 7" Slammer and it stays on top great but I've had no luck with it so I moved up to the 9" and was hoping for the same swimming results....I can't afford to keep buying Slammers so I'm gonna try and get a return on this one.....BassMan
