I would, but honestly it is like gambling. You should really use OCV + temp correction factor for the coldest ever temperature in your area. Basically what happens if your panels go open circuit on a really cold day? You end up with even more than VOC and fry your charge controller. You never want to go over on voltage. There has been a lot of debate on amperage, but zero on voltage. I think everyone agrees going over max pv input is bad. I think some controllers do have safety margin built in, but others have none because most manufacturers are going to want to put as big a number on their product as possible.
My controller for instance is rated to 2000w pv input and in theory my panels could generate 2500w+ on a perfect day, when the panels are freshly cleaned, sun it at the perfect angle, temps are burr cold, etc, but I have yet to see that day in the six months I have had the system running. My panels have a VOC of 37.6 V (3S=112.8v), but the highest number I have recorded is 103v. That is still significantly more than the panel rated 30.3v though, so I would always use the higher number and maybe round up as well to account for cold temp. Another way to do it (and probably the most conservative) is to use normal panel voltage and the controller PV voltage range. My LV2424 for instance has a PV voltage range of 30-115v (max 145v), so I used 3P which comes in below the voltage range even at VOC.
Anyway sorry for rambling, but I think 3S3P is going to be your best bet to get the highest wattage number unless you pick a different panel spec. If you only have 8 panels and cannot get another one, you could always do 4P2S (~60v, ~40a) but you would have more (and bigger) wiring.
