I good static tip is hard to beat IMO. I've had a couple and have been much impressed with them. For my dollar, I prefer them over non-static.
I will say this though, I poorly designed/inefficient static tip is no better than any other limb. Being a "static tip" is kind of trendy but without doing some pretty good research and development it would be easy to turn out another "vanilla" limb.
Please understand, in no way am I implying that South would do that. Just stating an obvious fact that consumers will rush to a great design and shy from one that's ho-hum.
I think it's a great idea and look forward to seeing (and shooting) anything coming out of the Stalker shop.
