As per other comments I have seen on the subject, the tower clamps on my Cyborg 2 didn't grip well even after screwing so tight they were at risk of breakage. So I turned to a solution to a somewhat similar problem with plastic (carbon fiber) bicycle frames - friction paste, sold under several names like Carbon Gripper. A thin spread of this on the inside of the clamps that bear on the tower tilt angle axle and the towers are locked in place with a lot less tension on the screw adjustment. Still adjustable, in case anyone was wondering, they just lock again when the adjustment screws are tightened.
The paste can also be put in any sliding adjustment with the same benefits. I pasted all the adjusters on the Cyborg in about 30 minutes - that's disassembly, application and reassembly. Resetting up positioning took about another 30 minutes, I admit, but the benefits of having everything stay where I wanted them have made the work easily justified.
If you go for this little mod, watch out for the teeny nuts those adjusting screws go into. They drop out very easily during disassembly and could potentially go into of those places such dropped items go to disappear. I suggest disassembly somewhere you can afford to drop and find such small items. I took the opportunity to put tiny dobs of BluTac on the slots where the nuts go (after they are inserted) to stop them falling out at the wrong time during future similar work.
