>>6620741>Prowl / Bluestreak / SmokescreenTheir shoulders feel somewhat displaced and the lack of leg swivels really hurts their poseability, but as far as looks go, both the robot and vehicle modes are great modern redesigns of the Datsun bros. One common problem to look after is the fact that the paint on the transparent pieces of Prowl (that is, the doors and roof) tends to melt off under prolonged sun exposure, but that was thankfully solved in Bluestreak and Smokescreen.
>Sideswipe / SunstreakerGreat robot and vehicle designs all around, wholesome articulation, interesting engineering twist by making each of them work in reverse with their chest. Really solid and fun mold overall, probably the best car robot back then.
>Hound & RavageAbsolute best kino mold in Universe, easily one of the greatest Deluxe CHUGs ever made and, as of now, still pretty much the best Hound around, at best lightly tied with the great looking but no so well aged Alternator / BT. I'd recommend you get the Henkei mold instead but, given how much those are appreciating nowadays, settling for the bogstandard Universe version is still going to land you on an awesome figure.
Can't say anything about Grappel because I don't own either him or the original Inferno, but there's alos a consensus of sorts that he's pretty good.
