how low is the low ceiling? i love to throw backhand rollers but you have to be very careful with low ceiling situations primarily because of the amount of spin you would have to generate to get the disc up on edge without throwing an arc/rainbow sort of shot.
i have thrown and like the jls but have not thrown the other 2 discs you mention. my personal favorite choice for rollers is the innova panther, a beautiful round edge on that disc makes not only for a perfect roller disc but allows for a very high altitude nose down angle without stalling. this disc turns beautifully and is incredibly durable, probably one of the most useful long life discs i have ever thrown over the last 14 years.
back to your question though, if you want to roll without throwing an arcing type shot with the left edge up at release (considering RHBH) then you will almost certainly need to be using a stable disc (not overstable and maybe not understable just stable) and keep the disc flat at release with a tremendous snap. also, remember that the more snap on the disc at release, the quicker the disc will stand up, roll, and fall over after hitting the ground, hence the need for a stable disc and not understable.
try a panther if you haven't already, borrow one from a friend if you need to, great natural roller just my 2 cents.
