I really hate to open up a new topic, but this is a really basic question that could be helpful to others to have it not buried in another thread. I'm just wondering how you change the shells on the G6. Looks like there is a small screw holding it together but is there any special tool needed to take it apart? And when you put it back together does it still feel sturdy? Just want to know if I should order a triwing screwdriver with my G6 or not. Thanks!
