SA3R's are the most Marmite wheel ever, so you will offend some if you run them. The Buddyclubs are the safe bet, everyone will like them, but you won't stand out. The Buddyclubs are also a fair bit lighter, the SA3R's are heavy as you know. Plus you already have the Buddyclubs tyred and balanced.
Lighter isn't necessarily stronger. I'm pretty sure the sa3r are one of the strongest wheels for it's size and shape. It's heavy for a reason.
Wheel weight is overrated too imo.
