I have to have Brooks saddles set with a very distinctive nose-up position. I cringe when I look at them (how can that possibly be comfortable?) but it works for me. Curiously enough, if the nose isn't pointing up into the air, the rear portion is angled downward and slides me onto the nose. With the rear portion level, the nose is up, and I'm comfortable - as long as my bars are high enough. Most people will tell you something similar, and freak out when they see a down-angle.

I have a good friend, though, who puts in tens of thousand of miles touring each year. His Brooks is canted downward at a severe angle - my shoulders would give out within an hour. He claims it is perfectly comfortable, though, and proves it by putting in ten hour days.

So in your shoes I'd play with the angle, using that good two-bolt post you bought, and not worrying at all about appearances. Chances are that level-to-somewhat-up will be best for you, but if you really do end up liking it somewhere else, more power to you!
