^not sure about the whip tip, but honestly the disruptive tip leaves nothing to be desired.
I own a full balance set and tips in every color. The difference in sound signature compared to other barrels IS noticable. The milling around the porting is also designed to keep paint out of the barrel for those who prefer to tape over them.
And to clarify, the deathtouch was designed to accept shaft tips. And between the balance and the deathtouch, the latter is the only one to offer a carbon fiber tip. (AKA poor mans csl tip). These barrels are sick, pick one up.
