Salt nic is diluted, therefore you can vape a higher concentration of it w/out feeling from it, a nasty burn, cough, or throat hit. A 50 mg (5%) salt nic probably provides the same harshness of somewhere between 6 and 12 mg freebase for me. That may be completely different for you. I can MTL/RDL vape 6 mg freebase with some level of tolerance, but it isn't anywhere ideal for me. The same can be said for 50 mg salt nic. I will certainly never try 12 mg freebase, as throat hit has never been anything I've been after.
So to answer you more directly, continuously lower your nic concentration using salt nic as much as possible (hopefully they still make low Ohm salt nics in 3, 6, and 12 mg). When you feel your vape frequency (how often you're taking puffs) has stabilized, then switch to 3 or 6 mg freebase. If you make the change too abruptly, you may find yourself chain vaping just to get your nic fix which isn't very ideal.
Right, so the varying factors between these types of setups are resistance (Ohms), Amps, and Voltage (and in turn Wattage/power since Amps * Voltage = Wattage). A 10-20 Watt setup is powering a higher resistance coil than the higher Wattage setups which are often powering lower resistance coils. Salt nics are usually found with much higher nic concentrations, so the method of delivery is meant to be in smaller portions. This is often why salt nics are recommended to be vaped in an MTL setup which are mostly correlated with low Amp, high Voltage, low Wattage, high Ohm devices.
In a higher Wattage setup, you're looking at lower Ohm coils which require more Amps, or battery power to fire the coil to the needed temperatures. Using 40-60 Watts, you're looking at a coil probably in the 0.3-0.4 Ohm range in resistance, as opposed to the 0.8-1.2 Ohm coil in the Onnix 2. In mini-pod systems like the Onnix 2 for example, it only has a 900 mAh battery. In the Innokin MVP Pod, you're looking at a 500 mAh battery capacity. A setup that requires a lot of battery power to run, isn't going to last very long - so you're not likely to see a high Amp, low Voltage, high Wattage, low Ohm setup in a mini-pod system. It's just not practical with our current battery technology if the device is meant to keep the user happy for a worthy amount of time.
When it comes to nicotine needs and delivery, that's going to be vastly different for everyone. I vape 3 mg freebase, and have purchased 6 mg freebase thinking how much different could it be? I cannot vape the 6 mg without diluting it. Now here I am, testing a mini-pod system for a future review using pre-filled pods with 5% salt nic; that's 50 mg/mL of nic. I don't take big long vapes, and definitely feel the throat hit, but this isn't ideal for me. It could be for you, however.
MTL devices are most often: high Ohm & Voltage; low Amps & Wattage.
DL devices are most often: high Amp & Wattage;, low Ohms & Voltage.
