My buddy has a 2 ski quiver - we ski in PNW at Schweitzer Mountain. He has a QST 92 and added the QST 106. Super simple for him to chose a ski. 2 inches or less - the 92. 3 or more the 106. I see a lot of QST 106’s at Schweitzer because they come in a tweener size of 181 and are easy to ski but perform well. If I were you I would look that direction potentially. The E104 is a good choice as well. Both will make your decision easy for you.
I have lived in a 2 ski main quiver for a number of years. A low 80’s and the Bonafide at 98 at the waist. Very easy to pull a ski based upon the conditions. I have taken the Bones in all conditions and all depths and they have never failed me. What they gave up in the first hour of deep snow they made up for when it turned to chop and crud. I just added a Kastle BMX 105 HP to the quiver and now my decision will be trickier. But by learning and skiing my Bonafide in all conditions and terrain - I am a much better skier. I don’t think that would have happened if I went straight to a wide ski first.
Thanks. I think QST 106 is going to end up as a very strong contender for me.
I have an old friend that is a former high-grade instructor and general world-wide ski bum whom I contacted recently (he was skiing Val Thorens at the time) to ask for advice. He didn’t recommend specific skis but said that to cover most bases for a Western skier, about a 15-20mm difference is a good general rule for a two-ski quiver and about 10-15mm difference works well for a three-ski quiver.
Anything more than three skis and one can start to specialize and get real tight or real specific for conditions or even skiing certain areas, he said.
So, I have patterned my search after his recommendations. I went 90 first, so around 105 - 110 for the wide ski. If (when) I decide to get a skinny carver, I'll drop down to around 72-82, depending on what I like. Should have most bases covered! Sounds like you and your buddy have done about the same thing.
