I also suspect those claims of "much more velocity and spring life" are not entirely accurate- Weihrauch has been pretty good about getting close to the maximum possible out of its platforms, and I have not heard of spring failure issues. Could be wrong- but it sounds more like a product being invented that may not have needed to be invented. _________________ ` I'd say "I care." But I'd be lying.
