So I got my new wheels in, the fully forged MRR NES FG-01, and I was surprised to find that they actually weigh .6 lbs more than my current wheels, the Forgestar CF5V, that are rotary forged, albeit being .5" narrower in width.
How is it possible that a rotary forged wheel can weigh lighter than a fully forged even when they're similar in design and mass?
Your forged wheels will be much stronger and resistant to bends/cracks. There are a lot of lightweight cast and rotary forged (flow formed) wheels that are fairly fragile and flex a lot under load to achieve lightness.
I remember reading an article where they actually measured how much different wheels flexed and deformed under high turning Gs. It was pretty remarkable. Some would result in 1+ degree of camber change.
