Chuck's Reviews Transformers Studio Series 86 Constructicons Hook and Long Haul
 

I'm a bit biased since Long Haul is one of my favorite Constructicons, but this set is really solid. Transformation is fairly straightforward, and I appreciate how dense both figures feel. Obviously, this set is a necessity if you want to complete Devastator, but both figures stand well on their own.
