I tried it and loved it straight away. All my balls, league and tournament has IT installed.
Last night in league, front 7....my IT snapped, the bottom of my inner sleeve and the bit at the bottom was completely smashed, kinda like someone had hit it with a hammer!!!! I had to change to my Venom, left a 9 pin and then struck out. 279.
Apart from this, I've put about 15 customers on the system and had no problems.
IT is so much better than Switch IMO for creating the same feel ball to ball, Switch was close to it but not as good as IT
