The springers don't dictate such a rapidly changing selection as offered by the PCPs and might seem stagnant. But why fix what ain't broke? I genuinely feel that the HWs offer such an excellent proposition as regards performance and quality vs price.
There's not much more I'd need a springer to do than what they can do now. Although I'd still love to see a nice, slick modern-day quality sidelever that is easy & safe to load whilst delivering genuine accuracy.
