WyrreJ,
17 & 24 seemed like a strange combo to me so I looked at the path/coverage after installing the new blades. The coverage seemed fairly complete & it looked like longer blades might actually hit each other at the bottom of the stroke. I'll stick with the stock size myself but others may have different opinions. I used to have a Samurai & the dinky little blades were hard to find (can't remember the size). I put larger ones on & they ended up digging into the rubber windshield seal.
