Why don't you like the special nade plugin? It changes a lot, but even then, worth a try, isn't it? And I guess it does not destroy the whole game, but of course the “old good ways to play”.
To me it sounds too overkill and differs too much from the original nade setup but what the heck, it's worth a try!
