I don't know - probably not an evil plot. #6 is really old, slow, and uncomfortable. It also bogs down quite a bit at times depending on your timing when you hit that lift. I'd say having a replacement is all good. Note that I wouldn't have said that previously before seeing the result of Chet's. Knowing that LL probably won't be increasing the number of skiers thrown onto the top of those runs gives me some comfort that they know how to do this right.
Chet’s did not increase uphill capacity, because Luv chose to use fewer chairs initially. They were very intentional. The belief was Catwalk/Mambo and the top of Spillway had traffic limits.
#6 is a double. Going to a triple or quad will increase capacity. But many of those trails are underused. Luvs plan explocitly says they want to increase capacity. With such a shallow pitch those trails stand little danger of being scrapped off.
Chair size also presents other challenges. Skiers have become wider over the years. So many folks presently find a double very restrictive—be glad there is no center pole! But triples are often treated as extra wide comfy doubles by many skiers, unless a lifty makes sure it all loads well.
Triples tend to have a slightly faster line speed than a fixed quad. Paired with a loading carpet the functional speed and capacity increases further. Many good or older skiers find loading carpets awkward. But, with most new skiers and contemporary lower intermediates having learned to ski using a magic carpet it seems to work well.
A HSQ+triple combo would be very similar to BMX+Lenawee at ABasin.
A common misconception is that a high speed detachable will increase uphill capacity. If you monitor lift capacity stats, that just is not true. Detachables require more space between chairs, and therefore move the same number of people up the hill. The ride is shorter, but that also means any wait is going to form in a line, rather than filling in extra slow chairs.
Luv has had lots of success using triples. #2, #4, and Ptarmigan are all triples. Making 6 a triple would fit that pattern.
Smaller front range resorts seem to have found a flagship high speed paired with all other fixed grips to be a good mix. Elders, Luv, and ABasin. Granby is the same I think. Moving to two HSQ would move Luv into another category, and perhaps a necessarily more expensive one to cover operating costs.
