Cutting oversized sheets of glass????

I need to cut down Kokomo's 32" x 84" sheet of glass. 106 sheets to be exact.

Basically my issue is ---I need to cut out a pc. that is 17" x 60" from every sheet.
I know how to cut the glass, BUT I'm wondering if there is a trick to breaking on the long score. (I can't have many mistakes.) The runners only take the line up about a foot in either direction
and pulling it to the edge of the table --- well that's a really long pc. of glass and my arm span is not.

Is there anything I can do to rig my table for breaking along the length or something I can slide under the glass to gently lift and break.

Glass is to expensive to have it break wrong.

Any suggestions welcome...
a local company here said "Cross your fingers and Pray," so I've go that under my belt.

Thanks,
Stephanie
