@Imperious:
I got about 3 of those. I really prefer dice tray. Towers suck because you got a small space to see the dice and if you roll alot of dice, it takes more time to count hits.
The tray is much better because everyone can see the results from the table and usually people like to count hits by sweeping those dice to the side of the tray. The tower really has no such space.
I agree 100% I got a beautiful wooden dice tower from FMG (yes they have them), however, when the dice roll out some dice kick back under the drop shoot making them difficult to read. I brought this up to them last year and I believe someone at IWNGU (I will never grow up) was working on a design that releases the dice higher so when the dice kick back, there is a bank that the dice will bounce off of.
