I don't think anyone has ever said "my bike is too light". The CHPT is drool worthy imo. Granted, I have a pakiT (and I'm not going to try to talk you into one) but when I bought it I spent money to get it lighter and fixed up the way I wanted, even though it seemed like overkill and a bit unnecessary in some ways. But the fact is, a year or two later, you won't be thinking about the extra money you spent but you WILL be enjoying the benefits of it. Pop for the bike you really want, you won't regret it. $800 may seem like a lot right now but amortized over the life of the bike (including resale value) it's not much and you won't be unhappy with a lighter bike.
