Finally got to put this bad boy together after getting Overload delivered yesterday; it's been a bit of a journey but well worth it in my opinion.
While every figure suffers from compromises - which is always the case with combiners and triple-changers - the set as a whole is fantastic.
I am most surprised with the stability of the combined mode. From pictures I assumed it was a rickety old thing that would come apart if you sneezed near it, but it's actually locked together pretty tight with a stack of tabs. Reasonably complicated too - I don't think I'll be transforming my way through this set from memory any time soon.
