I have a dual Russell with heavy suspension front and back on my C10.
For comfort they can't be beat on the C10 (IMHO, obviously).
I have done 1000 miles in a day solo, and 600 miles in a day with a pillion.
She loved it so much she paid for half of the Russell we had on my C14.
Unfortunately we had to sell it (and the guy I sold it to won't sell it back as he says his better half would kill him) but I will soon have a Russell on the C14 again. :-)
Now, if yer into serious sport riding don't bother as they make it damned difficult to get off the saddle but for cruising or touring the Russell is THE saddle.
