Thanks for informative/constructive posts. These are the kind of posts that people need. Not the ones where people get going back and forth about how it is stupid to this or that and you're an idiot kind of stuff.
So thanks again for sharing what you did/tried and the results you got. I tried searching before I drilled my single hole and all I found was a few threads where people were going at each other about it didn't make difference, it does make a difference, blah blah blah. Sorry but forums like this should be for people looking for first hand knowledge of a certain mod and peoples experiences.
