Went out looking for Mixmaster and Scavenger today. Obviously didn't find them, but both Targets had Megatron and Grimlock, first time I've seen SS86 G1 Grimlock in person.

I just paid my phone bill so I couldn't justify buying a Leader figure right now (I would have only bought one Contructicon had I found both of them, but wasn't expecting to), but I do want Grimlock. The thing is based on my experience with SS86 Sludge (the only SS86 Dinobot I ever found in stores), I imagine SS86 Grimlock needs SOME form of upgrades or fixes, but it seems both Nonnef and DNA options are no longer available.

My question being how does Grimlock compare to Sludge as far as needing "fixes" go?
