That easy cocking system is amazing. I didn't think there would be much of a difference between the stock and the new version. But when Tom was gracious enough to let me play with the HPS 30 for a while the cocking was extremely noticeable! That alone is well worth the upgrade. The external adjuster is nice when you are tuning, but when you have things set, like you said, there is really no need to adjust anything. If there was a way Tom would be able to make a regulator like the Leshiy's use that would be great.
