Oh, I completely understand and appreciate that it's mostly marketing at it's finest, and that some new "technology" must be presented with each season's new frames.
I don't mind the IGS system at the throat of the rball frames. It can be awkward accessing them while the frame is mounted to the machine, but pretty simple if you prestring the mains before mounting. It's not too difficult, considering that all mains will be tensioned at the head. But to put the IGS in for the crosses too didn't make much sense to me - especially from a stringer's standpoint.
From a playability point of view, the IGS models were very well thought of, players loved them. However, they broke...very easily...very frequently.
The 165g model was quickly discontinued due to it's nature to almost self-destruct. The IGS system in the crosses was also discontinued at the same time...just a coincidence? I don't know that the IGS system in the crosses provided for a stronger, more durable frame. More powerful? Perhaps - I can't really comment on that.
