Toupes are plenty aggressive, they're just flatter. The way the sales dude explained it to me, they're for people who move around more on the saddle (which I thought was me) so I tried one. Hated it within 3 miles. Tried some Fizik saddles and ultimately ended up with a Romin evo. You wouldn't think they're that different but they are to me!

Ask them to let you try a demo saddle - you just paid for a fitting, it's the least they can do.
