This why I like 2-bolt seatposts and have them on almost all my bikes. Changing seats is tedious but making small incremental adjustments that are easy to track is simple, requires no measuring tools (protractors, levels or straight edge and tape measure) and every setting is repeatable. Need the nose down? Stop (yes, mid-ride adjustments are easy), loosen the rear bolt, tweak the front say 90 degrees, tighten the rear and ride. Too much? Go back 45 degrees.

Additional advantage - get a saddle sore but need to keep riding to get ready for that century? Tip that nose up or down say two whole turns 'till you are off it. Yes, far from ideal but it heals and two weeks later you can go back to exactly where the seat was before.
