I am one of those that rides with a slight “nose up “tilt to my saddle. When I get a different bike I always start level and then slightly adjust the tilt every ride until it feels just right. I also like a short cockpit or top tube , but a tall frame because I have long legs and short trunk. Almost all my vintage road bikes are racing bikes not because I race, they are just real comfortable to me. It takes a lot of riding to find that spot that works for your body type . I recommend slight changes and only one thing at a time. There are a lot of factors that make up a comfortable ride when riding over thirty miles or so at a time.
