Step up or Step down

The Tapeless One
Ok guys, If i have a 77mm lens thread and wanted to buy the Letus Extreme, is it the best to

step up from 72mm to 77mm

or

step down from 82mm to 77mm

Which would give a less distortion to the image (vignetting ...etc). What other possible problem could occur with

a) steeping up

b) stepping down

thank you in advance
