Is anyone using a Russell Day-Long saddle? If so, did you use the "ride-in" option to have the seat customized in one day? If you didn't use "ride-in" option, how long did the process of buying and customizing the seat take? Are you happy with it on longer rides (i.e. 500+ mile day rides)? Would you buy another one? Inquiring minds want to know! Thanks in advance!
