Both advice from Frog and common reasoning tell me a center stand is essential. The one without the extra piece comes from Dual-Star, is more expensive. I like the picture and want a clean look on my bike. Is the extra leverage from the "lift arm", or "lift foot assist lever" a good idea or a gimmick? Is the center stand skid plate a good idea? Which source(s) have the best quality center stand? Thank you.
