optiwhite

hi! I'm in the prosses of making my own 200 gallon 6 foot by 2 foot by 2.5 foot tank. i wanted clear / low iron glass in the front pannel and regular glass in all other sides, but my LFS told me that is not possible as "clear glass is weaker than regular glass" and i have to get a full clear...

I'm looking at getting a 8ft tank custom built, and I have the option of getting optiwhite. Does it make a difference? It costs a lot on a tank this big - question is - is it money well spent?
