Here are the latest version of the Limbsavers to come out. I stumbled accross this on the realtree forum, This is a quote from and email from a Sims employee.

"Everything is being introduced at the Archery shows. What we have are “ultras” and a new kit for crossbows for both the split and solid style. The ultra reduces limb shock and vibration by a minimum of 80% and reduces noise by up to 20 db. They are built differently to help with more movement of your bow as well. Our new line will out perform all of our competition and is a major improvement over our previous limbsaver designs. If you give me your address I will be more than happy to send you out a 2004 archery catalog. "
