||I've been running a drive-side Overguard for a few years and decided to get a NDS one to replace a plastic guard.
These are solid and give great coverage. I love that they protect the droputs and the anti-roll pins are a helpful addition.
A mod: I've found that I can get the anti roll pin to match up to the drillings on some chromo pegs by removing the washer, so the head of the bolt sits proud of the front of the guard. It takes some messing about, but gives a bit of extra security against peg spin on the left side.
Running LHD - Tightening down the peg on the left side, I have to make sure the guard is properly positioned, otherwise it moves when tightening and can rub on the chain - not a big issue though.
I have some issues hanging up on the guard during double-pegs grinds, but that's my sloppy technique.
The design is great and will probably outlast me. They slide really well on all surfaces and will probably fit 99% of setups.
