So I noticed a lot of people recommend legs, but I honestly don't like them. They are kindof a medium/slow higher power part. I like wheels a lot better because they are at least 20 faster to 40 if you go plain "wheels". The trap triggering goes down to 50% which is better than the legs or treads. At 75% and 100% respectively.
I would rather go full on treads than legs because they at least have the hauling capability that legs don't. Even weak Com. Wheels carry more (and you find them off of scavengers)... what am I missing?
