i was planning on making the holes oval to allow a smoother route, but i am concerned they may weaken the bars. the bars are steel, narrow, and very stiff so i reckon it would be alright.
That they are steel is in your favour, but making the hole oval is a bad idea, this is a bigger stress riser than a perfect circle.
