In reply to echo34:
MX has been my old workhorse. It works really well for dry'ish scottish conditions and summer Alps (plus ice climbing in Norway or Alps).
But in the Alps, you need to go high and indeed it can be "too" warm during sunny weather rock climbing.
Another contender would be Patagucci Knifeblade or the newer model Kniferidge. I got the Knifeblade to replace my beat up MX and patagucci Mixed guide for winter climbing this year. Thus far, it looks to tick all the boxes I want...
Oh, and BergFreunde has the Knifeblade at a nice discount (provided they still have sizes).
If you're lookin' for something a tad lighter, patagucci Leviation might also be a good contender.
