I am going to take what might be a minority view. Friction is great but index is demonized by Rivendell way more than it should be. I have found 11 speed friction to be more finicky than its worth. If it were me and I wanted 11 speed (which I do have on more than one bike) I would stick with index as it works better IMO. If I wanted to move to friction I would also move to 9 speed. 11 to me is most useful for a 1x setup. With 2 in the front 9 is enough and works so beautifully with friction. In fact if my fictional Roadeo allowed it I would go to DT silver shifters (although bar end would work just as well especially if there are no DT accommodations) and that new fancy reverse shifting RD. Then just get the absolute most comfortable brake hoods you can find.
I have not tried friction on 11 peed however its noticeably more finicky with 10 speed than 9 speed I can imagine the difference when going up in speeds .
