OK, I by no means disagree with you, but to put you straight on a few points:
- You may not have to change the batteries for 3 years, but battery usage is based off of the intensity of use. If you play perhaps once or twice a year, you'll be fine. If you play every other week, it's a different story. (alternatively, if you're me, you'll leave it on for a week without noticing)
- "Super thick shell, yet still light." Yeah, but it's by no means the lightest out there. The Prophency (Z2 at least), Pinokio and Spire are all lighter.
- Yes, it is able to keep up. But, likelihood is that you won't be shooting at the Rotor's maximium advertised 50bps. The most I've ever shot at is around a 17/18 on semi auto, and that's only 'cause the guy wouldn't go out.
