Hi and welcome. Only you can pick your juice. That said, high wattage use requires good wicking ability. In general, thinner juices-- lower VG, higher PG-- wick better, all other things being equal. Low VG, high PG also means more throat hit and less visible vapor. The ability to wick is more a function of the tank and coil design, and the wick material, than the mod or the wattage. The wattage sets the requirement for juice transport, the tank and coil set keeps up... or not. You'll know if it isn't, I promise. If not, a quick fix is to back off the watts, to get the requirement down into the range the tank can handle. In the long term, it might mean going to an RTA, becoming a coil builder, and wicking rayon.
