It's the resonated version, purchased June 2012. The tips were lost due to the fact that they were held in place with the supplied circlips, which being made of thin steel, gradually fell to pieces causing the tips to come away (I never found either one, unfortunately).
I am aware that Cobra Sport are aware of this, and provide uprated circlips.
Obviously the price would reflect the lack of tips as these would need to be sourced, but I believe these can be purchased by themselves from Cougar Store.
Any queries, just ask
