They couldnt help to the point of noticing, but they help have more glue surface area in the corners for some strength...definitely help out but on a pretty small scale I would saydo the 45's help much or are they just kinda placebo?

I guess I have a bit of ocd.//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
