Quick update - I took the jump and went for the NXG's with the Speedplate 2.0 inserts. Started to feel good after my fourth time out on them. These things make skating feel like a whole different experience. I guess I just never realized how poorly sized my old X40's were, but these are really helping my confidence on the ice.
I also hadn't realized the first time I looked at them in store that the pair they had on clearance were NXG Pro's, so these came with the LS3 steel and a different tongue, eliminating the composite tongue insert. All in all, I think I got a pretty great deal on a skate that is way more of a skate than I would ever be able to justify buying new. Thanks again guys for all the feedback!
