Congrats on the new Versys. I too was out of the sport for awhile (13 years) and got back in just before the Versys came out. I had a V-Strom 650 from 07-10 until a deer totaled it last summer and I cashed in my insurance check for a "used" 08 Versys with 250 miles. 1 year, 10,000 miles, and 2 sets of tires later I am still thrilled every time I ride the Versys. I would love a Ducati Multistrada, but for a third of the price the Versys is a better value by every measure.
As far as your seat, I had Sargent redo my seat to my specifications. I cost about $350 and took three weeks, but there is no way my butt would have survived 3,000 miles to CA and back on the horrible factory seat. I actually had mine raised 1" so I am not sure how your lowering needs would work with their process but I love the results from my mod.
Look forward to seeing you on the road!
