Alright Cary, let's talk Wreckers.
*Takes a minute to go take a picture of his current wreckers shelf to use on here*
Now let me start off my saying this is not my definitive Wreckers shelf. Some guys just ended up there because of space and others didn't make it for the same reason.
Now the backbone of my wreckers are the voyagers. T30 Springer, Sandstorm, Whirl, and Roadbuster all stand there, as does TR Broadside. TR Kup, Topspin, and Twintwist for the moment fill in the deluxe spot, while the FoC Ruination stands tall behind them. Roadburn kinda ended up there.
As I only have the TR Perceptor, he will stay with the LL crew (who are all pretty spread out right now because shelf space), and Whirl may go back there too since he is part of the combiner and I prefer him as part of LL. Your generations or Mulgan(can't remember how to spell it and don't wanna look) will go good with the wreckers though! Scoop is a good choice, though I intend to keep him in the Autobot shelf for the moment, but he will work as a Wrecker when I get the space. Blurr, the generations one may be the best fit for Wrecker material, the the TR/Legends one for another spot.
As for Kup, it is tough, but you could use the Generations one for the Wreckers with his hardened look and the TR one for a 86 movie shelf with TR Blurr
