4.10's + shift points

I've been thinking about getting 4.10's for a while (with TL of course) but I was looking at the tech articles and it says the shift point in 3rd would be at 97mph. How would you do a 1/4 mile pass, because I thought it could cause damage to the OD band if you shift into OD while your on it?

With 26" DR's on the car, I cross the traps at approximately 5500 rpm in third gear with 4.10's. My trap speeds are usually in the high 98's/low 99's.
