After trying Elixirs years ago and not liking them gave them another shot now while restringing my Ibby after I fitted a RY neck in it. With all the good talk about them here it seemed to me like I should give them another fair try since I have changed a lot since last time. Before I had the BKP Rotosounds on it.
What I can say is that yes, they do feel stiffer to me. Not just stiffer than the Rotos, but generally for strings. I am one who likes roundcore over hexcore cause I do not like the stiffness the hex provides. However, this is a different stiffness, one that actually does not feel bad. I will deffo get some again, cause they play nice, though not as nice as nickel on roundcore. To be fair though they are really different, so saying one plays better is kinda weird. I enjoy them both for different things.
I do feel they sound a more low mid focused than what I had before too, but the high end tone really seems to stick, so far I am impressed in that regard. Nickel on roundcore seemed to have more high mids and high end, but especially the high end fades as we all know. The price does seem justified for me as you might get a little less tone, but a lot longer tone.
For someone like me who playes multiple guitars these are really useful cause I can keep good tone up without changing strings all the time. And if I need really good tone for special ocassions or my favorite guitar I can always use nickel on roundcore.
