Thanks for the feedback, guys.

I am not the tallest bloke and have relatively short arms. I still find the stock handlebar height too low though. Especially for standing.
For the moment I have to lean a bit forward when sitting in order to get a nice relaxed angle on my arms. That's why I was looking at moving the bars slightly back and up a bit.

But given the possible cable issues I will probably just stick to raising the bars a tad. Will be cheaper as well.
