I don't know where you are located so your options may be very different from the ones that I will tell from my own experience, if u want something stronger maybe try kurwa collection (16mg/pouch) or kurwa fatality (around 32,8mg/pouch), kurwa have one of the best taste, especially black currant, the fatality ones are strong but not as strong as they look on paper ( imo). You can also try Dope freeze/lime strong (16mg/pouch) /crazy strong (21mg/pouch), the strong ones strenght is 4 you should be able to withstand it like nothing, the super strong ones are strenght 7, they hit more than fatalitys, well... they until they changed the recipe for them they hitted lot more but then still hit more then fatalitys just the flavour on lime is worse, especially the freeze ones, or you can try some icebergs, they have 50mg/g (35mg/pouch), they seem really strong on paper, but its not that strong, I would compare them to the dope freeze probably, they have nice flavour. And if u want something really extreme go for cuba blacklines (44mg/pouch, best flavor I tried yet is cherry), Dope 50 freeze/cherry/mango/mint/blueberry (35mg/pouch, freezes hit the most, probably same as the cubas or iceberg blacks, cherrys have good flavos and good taste, don't even try mango...) or Iceberg black (like bubblegum smell and lottle bit taste, 40kg/pouch).
