In reply to chris tan: These don't seem to be about any more but the new Wild Country Oxygen's have the same nose profile.
This though can cause some problems with multiple items on a frabs such as wires, where they may slip past the nose and off, where as with the normal nose krabs these with hold most of the wires stopping them falling off.
I think its a two way think. The best thing to do if you want to try the cleaner nose profile is probably go to a shop and see how things such as wires hold on the different types of krab.
