At 155 pounds, I have no need for 1.8s on wide flanged track hubs. I use them for my winter/rain/city wheels because they are cheaper, more rugged (bike rack accidents, etc.) and slightly less appealing but for the road, hardly a benefit ever. With the super wide flanges, track wheels are very strong and rigid side-to-side using very light spokes. (Basic engineering - wide flanges = well braced triangle. Far lower loads on the spokes when you load the wheel sideways.)
