What should I buy? Frame wheels cranks bars tyres mudguards grips pedals spokes bike

I'd just go with the ACI, based on price. There really is'nt much difference between them. My favourate are the Sapim Race. But again the price difference is in mo way justified IMHO.

DT comp, Sapim race, Wheelsmith DB 14, Pillar PSR TB 2018, and ACI DB are all roughly the same weight, all look the same, and have comparable strengths.

There is a post by mdcctester somewhere where he mentions some Sapim spokes that are the shit (CX-RAY from the look of the weights), and more or less says get those ones or get the ACI's as everything inbetween is basically the same in terms of weight and quality. That may or may not be worth something, but it would be worth looking at the weight differences between those spokes. Especially given the degree to which expensive spokes add to the price of your wheel build.

Also I'd look at the new Velocity A32's, as they're wider, or some of the DT rims. Especially given all the recent interweb rumours about OP's recent variation in quality. Plus they come in more drilling sizes if you're getting mach hubs.
