Since there are no Menards in my local area, my response may ultimately be based on shipping for what I may be interested in. Since track is heavy and one of the items I'd consider (long straights) are also bulky, it may not be economical.
Even if not a full case, I may order some short 10" straights just to compare and see how they look together. I tend to like larger diameter curves (54, 72), and based on the comments on the main Menards track thread, I'm pretty confident I will not like the lower number of ties for those vs Lionel curves.
