I needed a little more reach also so i sent my 09 electra glide seat to MCC and would highly recommend them. i had the front narrowed a little and the double decker memory foam added to both driver and passenger. my wife can ride 12 hours with no problem.
Can't speak to the MCC mod but I've been happy with my Mustang super touring seat since I got it. It does move you about 1/2 inch lower and about an inch back.
