Ernie Ball 2228 Mighty Slinky

I've been always told that heavy strings are good for you. I believed and tried to play with sets like 10-46, 10-52, or even 11-56. And I was wondering why it was so hard to play bends and bar chords, like an F major :)
...and then I realized that there existed lighter gauges, and for a good reason :)
Pros of light strings:
- less tension in the left hand;
- more accurate bends;
- you'll develop lighter touch and play faster;
- you'll love your guitar more because it's so comfortable to play :)

I don't really know what heavy gauges are good for. More sustain? More output? Having better control and less tension seems much more important to me.

My guitar is 24.75", standard tuning. I totally enjoy how it feels with the 8.5-40 set, I don't even want to sell it anymore.
