My wife seems to like the sprung pillion and I like the Deluxe solo, tho I would go for the "Premium" version. I have the tan solo which does not, of course, match the black pillion. So maybe you want to go "black". I cannot vouch for the Lycette seat for the driver. My wife only weighs 105 in her b'day suit, but I think the extra springing action is gonna make any woman happier compared to the stiff suspension on the Enfield.
We have not yet made epic journeys on the bike together, perhaps 50 miles each way. Personally, I cannot envision stting on any saddle for more than 100 miles at a time. Even on my Beemer I got off and stretched and butt-scratched by that time. Even in the car I have to get out and walk around a bit after two hours.
If you get the Deluxe you might want to consider the 3" springs. The stock 5" springs were a far reach for my 30" inseam and the side-swaying was unnerving at times in a corner.
-Jesse, spring has sprung, but summer is not yet....done!
