This is an extract of an e-mail to a friend, it illustrates a little of the weight weenie angst and madness at compromise!
I bought a nice light frameset to start the project. I then got a great pr of stiff light bars at a price i could afford. All was well and on track
My angst of what wheelset was effectively solved by me finding a new rear ENO on an Open Pro clincher and sprox. It was too good to ignore, but now has lowered the bar with fastidiousness regarding weight. Its always going to be heavier than if i had built with tub rims, though i take a little comfort from Harry R saying its the very best clincher rim. My LBS has got a pr of Schwalbe Ultremo ZX tyres for me. They have a little puncture protection and are 190g, so with a latex tube it will be durable and not too rim heavy.
The madness started with the brake levers. I really like the Campag Record levers that you have, they look great, and they are comfy to hold when you sit on the hoods. I seldom use the drops, and the hoods is def my default position.
A mail order outlet had the levers for £99 delivered, and i had told myself that i really wanted them, but as Xmas was expensive, i waited for another payday. When i had some money, they had gone up to £129 so i had a sulk. I then looked at SRAM 900 carbons. they were not as pretty, a bit heavier, and a bit cheaper. I then got to thinking that 40g heavier was saving me about £40, and so i looked on forums and saw Cane Creek levers again a tiny bit heavier and £40 a pr. And i discovered that Tekro are the real manufacturers so you can get them for £25 a pr!! So i agonised about the cost per gram ratio and made little lists of pros and cons and then just sat still for a while. Well to cut a long story short, my LBS will do me a Pr of the Record Carbons for £100, so i have ordered them!!
The Record levers are out of stock and unavailable, so I now have the SRAM S900 carbons. They do look very handsome in the flesh!
