I finally decided to start with the Selle Italia Prolink Light Genuine Gel saddle (144mm) in blue because it looks to have the flattest area at the back of the saddle so my sits bones should be making better contact, but still getting the narrower nose. Another selling point is that it's slightly wider than my current Selle Italia Flite Trans Am saddle (140mm).

However, the Vitesse Twin Tech will be my second choice if it doesn't work out. I may buy it anyway just to have something for my other ride. Thanks for the input, it always helps.
