I remarked to a friend once how hard it was to remove the lid, so he gave me a pump. The first time I used the pump I popped myself in the lip with the lid it came flying off so fast. Now I just don't push the lid down tight (3010), I just push enough so it is snug and even. I can easily get it off with my fingertips working around it. I haven't used the pump in a decade and I never have any leaks. I suppose if you use a full Jobo setup you might need to fix the lid more firmly with the cogs and all, but I use a Beseler roller base, so it all works fine for me.
