Went ridding last week end and my a$$ still hurts. I think I need a new seat. I think I've narrowed it down to either a WTB laser V progel on sale for 50.00 or a Brooks B17 for arround 80.00 The WTB is much lighter at 300g and the gel is suposed to be very comfy. The Brooks is an interesting concept and I have heard that its the last seat I will ever want but weighs over 500g. What should I do?
