The 18 lbs. of vertical load you are aiming are simply a yoke to copper capability.
I sketched two cross sections of the fins of your block, yust wuess who is more able to bending?

As the center fin treatment is my suggestion, I will attempt to defend it...
I suggested that to ease machining (going in one direction is easier/more reliable than going around corners). I also suggested going to a solid top concurrently. If Ben had decided to stay with a plastic top (this was originally my idea, as he didn't specify anything about the top in our initial communication), I would have suggested going back to the original setup. I hope this alleviates your fears.
