I think the main reason anyone does any type of drivetrain the way they do is because they have access to resources that make their design optimal. A sheet metal chassis can be done excellently. So can a welded tube chassis. Rather than sketch an exact copy of the best, drive design should play to the resources your team has. What use is a drive that's 5 pounds lighter of it takes you 2 weeks longer to build it?

We use a Poof inspired but *highly* derivative drivetrain that plays into our resources and goes together relatively quickly. It's light enough. It's definitely strong enough. Probably overbuilt. And it works because it uses what we have and what we were able to get in an offseason.

The way the Poofs do it, when you get down to the details of their bearing blocks, custom wheels, etc. takes a lot of resources that not a lot of teams have as readily available as 254 has worked hard to have. Play to your strengths.
