Will there be any noticable difference/benefit in changing crank arm length from 172.5 to 175?

Specifics:
Me: 6'6", 255lbs
Bike: circa1992 Cannondale 2.8 all Al (68cm)
Drive: Shimano 600 w/172.5
Mavic Cosmos wheels

Approx: 80-100 miles per week, flat, AVS 18.5

Thanks

Princess or pea?

At your height, a whole bunch of people will jump in and say "go longer." In practice, some people claim "huge difference" from the 2.5 mm change you're contemplating. Others say they can't tell the difference. YMMV :)
