Yes the Alcan springs many have purchased are a better made spring..... but it is not the right choice for a growing number of owners that are fully considering all sides of this "agree to disagree" topic.
In the opinion of several non-involved spring vendors, for our OE2 trailers, replacing a 1750 pound spring with a more expensive 2700 pound one is an expensive effort to achieve an oversprung load. Not saying that doing so is bad for some frequent extreme off-roading boondocking users, just that for the fleet in general, it is NOT believed to be THE recommended solution.
So instead of repeating the same confirmation bias we have heard on both sides of this issue, let's just sit back and see what OTT is going to use on their future year models. My guess is that it will NEVER be a 2700 pound rated 5 leaf spring for the fleet in general use by OE2's. Why? Here I go again... It would be oversprung for general fleet use.
PS: My Dexter PB-4 2400 pound four leaf springs fit perfectly and are doing just fine.
