Innova set would be fine for your son.

For yourself, I'd highly recommend an MVP/Axiom set, or the Latitude 64 beginner set.

The DD set you linked was my first starter set and I moved on from it very soon. Nothing really wrong with it, just not a fan of the feel of the discs. The MVP and Latitude 64 sets were much better IMO.

If it was me, I would get this one instead:

Or this:

IMO the Innova set is fine, but the Aviar putter is way too light and it sucks IMO in that set. It's way too light for putting and just sucks and doesn't stick to chains and just slides out or doesn't have enough weight to sit properly.

I would highly recommend the Latitude 64 set for yourself. The Fuse is going to be your new best friend.
