On a regulated mod the resistance is not important, but the coil mass and surface area is.
The performance of an atomizer is about the relationship between coil size and position, airflow, power and wicking. It's complex, subtle, elusive, and there is no magic formula. You need to be patient and experiment to fine tune the factors involved to get the vape you want, and sometimes it just won't be possible because of a limitation of the device you are using.
Also, why is going above 55 watts important? Wattage isn't the measure of a good vape.
