script algo is not a good choice now, maybe some anti-asic algo will be good choice like Xevean, C11, etc
those you have mentioned are also Nicehash resistant algos as well

I really love that part when some guy spends 100 bucks just to split the blockchain in two and make a bunch of orphans for himself. Also AMD cards seem to fail at those completely. Unless I mistake them for other algos like tribus or bitcore.
