Snus is really hard to get at a good price because of the taxes- I prefer lower strength 8mg but others swear by higher strengths - but then I also like the flavour of the lower strength over the higher ones most of the time
Mini portions can also kick like horses so dont let the physical size be the decider - look for the mg instead
If you are undecided - I wonder if you have tried vaping? You can have low strength with that also - actually lower than snus
WTA (Whole Tobacco Alkaloid) ejuice is also available for vapers who have trouble getting snus or who are having trouble switching to vaping - although I have found that WTA is not as strong as snus - so maybe that could be your ticket?
