It's easy for us to argue the finer points of upgrading your gear. Lots of talk about whether or not minor weight savings are worth the expense, and lots of talk about saddles, shoes and bar tape/gloves as contact points. But still many folks seem to persist that their 20 dollar walmart wicking tees are just fine, and Assos is a ripoff, etc.
So have you ever branched out and splurged on a really nice jersey and said, "Well, that was a waste; this isn't any better than my 40 dollar lime green jersey I got at Performance."
I'm gonna guess no, but would be wildly interested in hearing people's experiences. You can probably guess where I stand.
