Ok .... so I was in the same predicament a few months ago...
I had a good budget for a new wheelset and started researching forums. I had my mind set on a light carbon wheelset with a profile of 50mm
After much deliberation, and good advise, I opted for HED Belgium Plus rims (Tubeless ready) with Chris King R45 hubs (the ones with the ceramic bearing upgrade), and Sapiem CX-ray spokes (not the lightest wheelset, .... but quality).
reason being, that on the rides that I do, it is always a loop and the wind is strong on most days .... I am now training on some hills nearby and my weakness is climbing ...
I was told (by several people), that Aero is good if you have the wind behind you, or are riding directly into a headwind, but is crap when the wind hits you sideways
I use Strava Stix (connected to Strava) , which gives me climbing speed on all rides ... I think that I have made a wise decision based on the new info/stats, and a bonus is that I am now using tubeless tyres (which I am very impressed with)
I still want Aero carbon wheels as they look cool
