Any one pushed the limits on the AI HMS light bracket?

On my current build I am using HMS brackets for hydra 64's, on my last setup I had all lights on a home made aluminum extrusion setup and 3d printed brackets and hung from the ceiling. On this current build I can't hang from the ceiling and I am using the HMS brackets to hold up my Hydra 64's but I wanted to use one of my Orphek bars. So I made some 3d printed brackets to attach it to the front of the HMS rails, it appears the weight is a bit much and I can see the plastic brackets flexing a bit that hold up the HMS bar. I will attempt this with a 3rd mount but I guess my question is, how far would you trust the plastic brackets on these HMS mounts? Is a little bit of flexing ok?
