Hey XL owners...I just installed the new springs on my XL that I purchased last month. Man oh Man do they make a difference. These babies are the best thing since...since...well, since the Egg itself. I'm serious...the difference is incredible and they are extremely easy to install. The XL was great to begin with but now its perfect. If you have been holding off on an XL because of the weight of the dome...wait no longer.
