Lee,

I don't own a Mirage SX but I have shot them...and I have set up several for customers.

One word....Quiet.

Next to the G2 it could possibly be the quietest short bow out there. Price wasn't too shabby either....around $400 if I remember correctly....which is significantly less expensive than comparable 33 inch bows.

I would also suggest that you take a look at the Mirage 33. Same basic bow without the fancier limb pockets and the Sorbothane....for about $50-$75 less, if I am not mistaken.
