That second video is consistent with my experience of a lot of Motiv gear.
I've got a 5 5/8" pin to PAP (pin down) QZ-2 and it's is in my top 5 balls of all time (still in my tournament kit - too good for league!) I used it to qualify fourth at Orange last year. I started outside 10 board and finished the day targeting 23 and it was the only ball I needed all day to shoot 2279/10. Yes, of course Jason Belmonte qualified first, but I'm sticking to my excuse that he is a much better bowler than me!
Anyway the point is that the ball is still very much alive and kicking after all these years.
I dusted off my TX-1 (yes, really!) and took it to league a few nights ago and it was too strong
on the wet/dry house shot. I have a Primal TV-4 that is still magnificent and a Cruel C-51 LE that rolls like new.
Keep 'em clean and resurface regularly and these balls just keep on giving.
