New tank specifications and strength, will it hold ?

[monza]

Been ordering a few new toys for my new tank should be fun.
Here is my set back and questions....
Increased my tank size a bit in length and my builder said it "should hold" but no gaurantee. So what do you guys think?

Tank Specs:

100 x 26 x 26 with water height of 24"
1/2'" starphire glass on three sides
2"euro bracing around the top
two 8 x 8 corner over flows

my options:
regular glass a bit stronger
5/8 glass plenty strong, no Starphire, really heavy, way more money
shorten the tank length
go with it, maybe add two cross braces

I'd happily go shorter and wider but the width is maxed out given my rooms specs. (makes my dinning room small/ better half unhappy all ready)

Thanks
Dave
