Using these as spares. I brake the high E sometimes more often while the whole set is still good sounding and in good (playable, recordable) condition. These are great for that situation.

The other scenario is if I put on a 46-09 set instead of the regular 46-10, I almost always tend to replace the high E for a 10.

Not much to say, durability and tone are pretty good.

Pyramids are great all round strings at very affordable prices.
