DC300 Had the Dark Speed X also, along with the Aerojet, last season. They were very similar. But, I also had the Dark Speed LS and it was the best Cobra I ever used! Tons different from the DS X, and with the smaller 450 head looked even smaller. I'm waiting for 1 more price drop.š
The thing with being sent this Aerojet is that I won't know how it sits until it gets here. Those heads were not all created equal. I had to go through the whole rack of them at GG in order to find 1 that was square at neutral setting. Cobra drivers have always been like that....different face angles from 1 to another. And it goes way back to when I 1st started using them with the SS380. TM drivers, & esp. FW clubs, are much the same way.
