You should immediately sell that 200T to me since you obviously have no need of it if you are looking for a case. I keep one 200T in each hand at all times. It makes some tasks like eating, driving or brushing your teeth hazardous, and it can be hard to run a 660 with a 200T in each hand too.... but you get used to it and there are lots of ways to work around it. While I'm awake all my 200T's are running at idle. You have to wear ear plugs, but it's a small price to pay to be at the ready. When I sleep I stihl keep one in each hand but i shut the engines off. I put the bar covers on while sleeping now after I lost a girlfriend last year when she woke me up. Thank god we've got a bandit 18".
Overall, I think the plusses outweigh the minuses for being a chainsawhands. Be careful with the toiletpaper though.
