Adam:
My very limited experience is that smooth/quiet is easier than fast. Getting the optimum velocity depends on fitting the seal and guide perfectly, cross-hatching the tube exactly the right amount and not over-doing the lubricants, especially the heavy tar on the spring. That said, it should come up some in velocity as the seal breaks in. But hey, you've done a lube tune and now, it's just a matter of practice and refining those skills. You are hooked for sure.
