Had the procedure two years ago at age 56, I have gotten back into riding the last year and half. Typically do my 18 mile loop 3 times a week and a longer 55 mile ride with about 4500 ft of climbing on the weekend which at 58 is enough for me. I've tried several saddles, the best I have found is the Selle Italia Gel Flow Max Flite. It has a cut out, you don't go numb and it is very comfortable. I tried the Selle Italia Prolink, I found it too hard after about 40 miles. I also tried keeping the Fizik Arione that came with my bike (LOOK 555) but I went numb and it offered little comfort. I ride a rode bike and after surgery about 8 months later I did the MS150.
One thing I'll say about the Da Vinci procedure is it works. You'll find once you start putting in the miles you don't even miss your prostrate.
