I would definitely recommend the Air hawks comfort seat been using one for years and have swopped it on to various bikes, better than spending on a specific seat and waving goodbye when you sell the bike. Air Hawks are about £100 quid. Last Friday I rode 140 miles to visit my mom and 140 back on Saturday, 7hours riding in total, started to get a bit achy the last hour on the return trip. They add between 1/2" to 1" on the ride height.
Hope this helps
