I'm looking for an Autobot combiner to balance out my shelf opposite FP Brut, and I've been hearing for quite some time now that RailRacer is one of the best. I missed a lot of the RiD days, Scourge, FireConvoy and UltraMags were my first purchases getting back into buying TFs (and that was post RiD). And they are still my only RiD figures. But due to all of the buzz, RR may be my next pick up. I'm mainly looking for comparisons size/scale wise. In combined mode most importantly, but also in individual bot and alt modes if possible. Also, I'm wondering how they compare/contrast in aesthetics, articulation/posability, and just how "compatible" they both are overall. Also, if you have any other nominations for Autobot combiners that can go toe to toe with FP Brut, I'd very much like to hear them. Since I already have FP Brut on the shelf, and Maketoy's Giant just about to drop (and FP Menasor rumored to be on the horizon), I'm hoping to even out the sides a bit.
