The reason Sims is so big today is because the original limbsavers product work, and they were the first. I think they are probably one of the single greatest inventions in huntingin the last 10 years (or whenever they came out). After the original limbsaver's, they've released a 101 other products. You can argue points on all the other stuff, but remember, they've influenced more new products from the original idea than probably any other!
