Starphire, should I get it tempered?

[hahnmeister]

Okay... the tank is 48x30x20" high... all 1/2"... front and sides are Starphire. The cost to get the bottom and back tempered was nothing... like $30. Im considering then, should I just get the front and sides tempered as well? I would imagine that it would eliminate the 'facing' issues and the need for a short-wave UV light to determine the 'tin' side and the 'air' side. I know I dont need it for a 20" tall tank (with 3" euro-bracing all around too), but are their any drawbacks exactly? I know tempered glass is stronger usually, but if you hit it on the edge with enough force... there goes the whole panel. Does the same hold true for Starphire when it is tempered?
