I'm 58, 6', 215 lbs and ride 60 to 120 miles a week. I've been riding a Cannondale CAAD10 3 alloy Ultegra.Just had my second Back surgery and am looking at the synapse for a more comfortable ride. Live in north fl where the roads are mostly flat with rolling hills. There are some steep hills to challenge but not many. I enjoy riding 70 to 100 on the occasional weekend. I ride in groups and solo. I've tried the di2 and really liked the shifting but I was happy with the Ultegra too when it was properly adjusted.Disc brakes don't bother me as I have them on my mountain bike.I'm not sure about having them on a road bike.I can get the mechanical ultegra rim brake model for $2600 or the disc.di2/disc model for $4050. Weight difference is 17.2 vs 18.1 lbs. I plan to upgrade the wheelset later. Is it worth the the 1450 price difference for the di2/disc. I'm sure I'd be happy with either. Was thinking I could get the Ultegra mechanical model and spend the difference on a better wheelset and other goodies. Your thoughts? Thanks

Here are links to the different models
