I was curious if anyone who owns a Dyna Ring would be interested in a group buy on some tungsten carbide bearing balls to adjust the engagement RPM of their Dynas? U.S. shops are just too damn expensive ($32

vs. $1 to $5 each ) so I'm thinking about placing an order to mainland China to get them at a decent price. The problem comes when others want to do it as well but they missed out on the great price break that comes with ordering from an overseas wholesaler. So, if you are interested, please let me know!
BTW, I also plan to look into finding a short spring which also, according to Rekluse's literature on their own products, will also lower the engagement RPM.
