You mention normal juice, im assuming you are talking about freebase nicotine with a higher nic content as you mention you don't like the throat hit it gives you, DTL vaping 10mg salts is quite high but if it works for you carry on, I use a 0.6 ohm coil in a geekvape boost for 20mg salts but thats more a restricted lung/mtl hit and vape at about 23w, im the same as you I don't use freebase nicotine as it irritates my throat and causes me to cough like fuck, salts work perfectly for me as I don't like or need the throat hit freebase nicotine gives me, all I will say DTL vaping 50/50 10mg juice, if buying in 10ml bottles must be costing you a fair bit of cash, as above I buy 10ml 20mg salts for my smaller wattage devices like pods / allinones, but for my DTL mods (predominantly squonkers with a profile mesh RDA) at 0.15 ohm and around 60-65w i buy 70/30 50ml shortfills and add a 10ml 18 or 20mg nic salt shot to them, this gives you a 60ml bottle of 3mg salts strength juice, just a suggestion if you decide to go higher wattage etc on a different device, or even try on your current device.
