Anyone use the new Teckel Maracker yet? - Hope they sell spare tails!

So, Teckel came out with the new Maracker Frog which is basically the Teckel Sprinker Frog with a different tail. The Maracker has a metal rattle tail while the Sprinker Frog has a soft, paddle tail. 

For me the Teckel Sprinker never ran right and having a down-turned nose probably caused that. With an up-turned nose it would probably ride on top better rather than dive and would push the tail down giving it more bite and having it run better. I'm not the only person to have problems with the Teckel Sprinker design, I really wanted it to work well but after numerous trips gave up on it. You'd think they would have made improvements to the new Maracker to counter these issues.

Wondering if anyone has used the new Teckel Maracker Frog yet and their thoughts on it.

Also, I hope they sell Maracker spare tails like they do for the Teckel Sprinker Frog because I'd like to try their tail on my homemade Whopper Frogs which use the Teckel Sprinker Frog Tail.
