I could be wrong. But I still think, what you like about the OC is the Limba-Spruce combination. Infinity, to me, did not have that kind of feeling even though it is the same plies.
I think, getting one of the blade makers to make you a blade that is:
Limba-Spruce-Ayous-Spruce-Limba
But is faster than the OC, would likely be the thing that felt the most like what you like about the OC.
Most of the blades that are bing mentioned with a Limba top ply are Limba-Ayous-Ayous-Ayous-Limba like the Offensive S or Limba-Limba-Ayous-Limba-Limba like the Stratus Power Wood, the Korbel, and the Primorac. Acoustic is similar to that Limba-Limba construction but the core is Tung Tree.
Personally, I like all those blades. So, maybe, you will like them. But, in my opinion, the unique feel of the OC comes from the way Limba and Spruce interact which you only will get from a blade with Limba and Spruce.
Nothing wrong with trying a ton of all wood blades. But......
