I have a SA on one of my three bikes I may pick up another one on sale which last through December. I doubt you will notice the weight but it is picky as to setup and the nose has to be elevated. How much depends upon the rider and how you ride. It could be an issue hammering in the drops for significant periods. But a more aggressive position allows the nose to be lower than a more upright position. The more upright you ride the more the nose needs to go up. At $100 you can sell it and get most of your money back. I recommend the Trueleather X model unless you are 200+lbs (I'm suspicious 180+ may create too much sagging) in which case the NSX. I weigh 139-140 and I ride the TL X. The SA main complaints have been premature sag. The Weatershed non X models have had this problem.
