I dont know dude, Those holes look awefull close together, I know you dont want to hear this because you have already spen the money, But I would be afraid they would break at some point and time. Maybe not soon but when you have forgotten about them.
Soupys are a little more expensive ( I think, I dont know what you paid for those ) but you dont have to worry about them breaking and there easily adjustable.
