I've been using D'Addario strings since mid 80's, and this is a great choice for anyone who work on or own multiple guitars, or want to change strings regularily for eg. repeatable studio sessions.
Both personal savings and the reduced impact to the environment are quite significant compared with individual guitar string packs.
I personally would prefer wound G-string like on EXL115w set, but unfortunately no such luck with these 25 set packs.
But the pros outweigh the cons with this pack, so this is probably what I'll be using from now on.
The coiled string tube makes perfect logistic sense, and with care and doing it slowly it is possible to pull individual strings out with minimal binding (sometimes does require a bit of "wiggling"), but if You have room in Your workbench or guitar-/accessory-/tour-tech/etc. case to install the tube flat and straight, that makes life a whole lot easier.
