I test drove a 2ss w/ MRC before the Z. SS 1LE wasn't available and besides I'm a vert type. I liked the firmer non-1LE-ZL1 more (more grip, more tossable, more stable, without any more harshness). Like Jerome, I would expect the SS1LE to be similar in ride and handling to the Z for $30k less with the bonus of a couple hundred pounds less weight and penalty of a couple hundred less HP.
Recommend you go drive both and decide for yourself.
