although I definately will not complain on number of u/g's that i've had, i never had on on the change from SL-GO or GO-DM but did have them in between. Dont really think that this rumor is true....when i got DM 2 years ago i walked to the F counter expecting it (from all the rumor's i'd heard)....but was given my J boarding pass to "have a nice flight"......

No complaints though, being able to use my miles when i want to, is already a benifit that I was ecstatic about......
