Nope, my OSP custom blade, I played with it long enough to know it is nowhere close to as good as any of the other three blades. The OSP custom blade that a friend had that I tried, it was months old already when I tried it.
The blades that OSP specialize in making, like the Virtuoso Plus, or the Virtuoso Off- felt leagues better than the blades where someone said, "I want a blade with these specific plies," that were different from the ones in OSP's standard blades.
OSP know how to make great blades. But the ones on their list are way better than someone who plays could come up with for OSP to make.
If you buy OSP, I recommend you buy what they specialize in. And not try and think you could come up with a better formula than they already have.
