I use this set 11-52 on a short scale 565mm Harley Benton RG-Junior BK Rock Series, to make it possible to tune in E and it is tune stable. Original the guitar had 10-46 and then it is the best to tune it higher. I needed to intonate after changing the strings since they have a higher gauge. I bend the strings a lot and it works fine. I had to clean off the strings when they were new with a cloth. I recommend the strings and I will buy them again.
