I like a sweet tobacco and Find Space Jam Eclipse (50/50 and I vape at 1.5mg) quite acceptable, so much so that it is the only tobacco liquid I use for subohm, lung hits. That's coz I'm sacred to shop around and most UK B&M shops cater for the fruity / dessert crowd so cannot try any other 50/50 tobaccos before I buy, so stay with what I like and I do like it....
If we're talking high resistance then I like a good RY4, but they're hard to find and one I used to recommend have recently had QC issues IMO.
Good tobaccos for HR and higher PG are hard to come by...
I do have a HR MTL mix I use but it might sound weird but it's what I use exclusively in a nautilus mini - SJ Eclipse 50/50 3mg and Hansen RY4 80VG/20PG 6mg (ordered direct, re-branded is always 50/50 and I buy from them direct as I want higher PG for MTL and coil life) mixed in equal parts.... It does the job, is cig-a-like and a bit sweet, not OMG I'm having a vapegasm, but solid, tasty and dependable.
I must stress however I'm mostly into bakery vapes and only use my tobacco liquids very occasionally.
