Aero rules on basically any IM course out there. Weight will never be a bigger factor. What might be a factor is wind but that is typically a pre-race decision and probably not an issue at IMC.
Chris, you’re probably right, but I think the conventional Slowtwitch wisdom to ^this^ has always carried the caveat “ ... unless you’re doing a course like IM Nice or something.” Like the OP, I have found myself questioning if it really is as simple as “always a disk” with just so much climbing on the new course.
My quick model on BBS, for example, shows that for me, every additional pound of weight on that course translates to one extra minute in my bike split. So ... if the aerojacket - which is, what, like 2 extra pounds, is 2 minutes faster than the 808 alone, clear. But Im guessing it might be seconds of difference between the two on that particular course.
The operative word in your response is "Chris, you're
probably right...." It's all about making decisions based on achieving a high degree of probability.
You're overthinking it. However, in defense of "overthinking it," I'll leave you with this:
It's far better to overthink it than to underthink it.
Last thing, given that I see so many triathletes carry around a few extra lbs of weight, there's your low-hanging fruit. ;-)
