I love the motion of the Marvel Pearl, but I don't want to pay 200 for a NIB without at least exploring other options. With that being said, I'm in the market for a pearl with a strong cover and a low rg core. I believe my best option is either a Respect or a Respect Pearl. Which one is the closer comparison? IThe Marvel Pearl did get down the lane, but the cover did read the lane from front to back and it was not a back end monster (due to the lower rg and strong cover)
It's possible I might even have both at some point, but right now I'm looking for this specific motion.

It's not necessarily a replacement, however I feel it uses R2X...the MP cover. I would put a control layout, like iamone said. For me it would be pin down...under the ring. 

The phaze I feel is another option.  The colors on that ball make it appear more skid flip that it really is..

As much as the optimus isn't a MP...it is the same cover on a symmetrical core...
