My bike already had Pro Taper's on it so I pulled the clamps off and took it to the hardware store and found washers that were the right size and stacked a few of them. I ended up with 5 washers and a tall seat.
Opened the rider compartment right up. It's cheap and easy to raise and lower until you find the right height. Even if you don't want to leave it this way it will give you a chance to find out what you like before spending a bunch of money.
