I guess they have to do something to change it up between the brands! most everything comes out of syntas factory. my SW mirror has been stored in the upright position since the day i brought it mind you always had the cylinder cap on and sat on foam to stop the spiders getting in (... lernt my lesson after a daddy long legs thought my 10" tube was the shiznit!). its nearly a year old now and my friends always comment on how clean it is and i have cleaned it once or was it twice? I feel sorry for your 10" greahame itll feel neglected once the new kid comes in
