KoL question...

Hm.. most of the advice on hardcore, I've noticed, is geared towards making subsequent runs shorter and shorter (days-wise) but assumes that pretty much all subsequent runs will be in hardcore/no-path.

But if your goal is to just get all of the hardcore and oxygenarian rewards (sans the oxy one for seal clubbers, which is PvP oriented) and then go back permanently into softcore, wouldn't it make more sense to do the HCO runs first since you're not going to get any bonuses out of the food/drink skills?

For example...
Normal > HCO-DB > HCO-AT > HCO-SA > HCO-PM > HC-DB > HC-SC > HCO-TT > HC-TT > HC-AT > HC-PM > HC-SA > Softcore
