Hi, My handle grip or side grip are slippery on my standard MoVI m5,when tilting movi up or down. Before i only had this problem when the rig became to heavy, but now i have this problem with only a 5D markIII on. I have read before on this forum that it's only to screw them harder, but in my case i got a "crack" because of over tightening. And even if it was super thight and the weight was under max weight it was slippery. Any god ideas? I have tried to fasten clamps and and screw in a camera grip into the clamps but wasn't a very big change. I have also thought about replacing the 25mm handle bar with a aluminum rod, maybe i will get better grip then. But hasn't found a place where i can buy one.
