Yes, I mentioned that in my review. I tried it flat as a starting point and adjusted it from there. the directions say that a slight tilt is how it should be for the plus. this just seems to be the position that feels best for me as of now. I'm sure I will be doing some more adjusting as I get time to play with it.

It is a similar shape to the SMP. The cut out seems to be much softer on the inner edge of the whole which is good for me. I was looking into the SMP before I purchased my seller Italia but felt the SMP was to hard for me. BUT this is also before my bum got accustomed to riding in the saddle and maybe u tested the wrong shape SMP considering they have like 12 different models to choose from.
