Never tried 555
I've tried western though - has some nice notes in it - almost bakery, but smothered in weird plastic tobacco - it was the last straw for me with TFA and tobacco. If you want a selection of TFA tobaccos, drop me a PM
I'm like you, I need a non-sweet tobacco around. I think INW absolutes and FLV's tobaccos are where it's at for dry tobaccos - even the INW aromes can add too much sweetness sometimes
Most concentrates have some kind of sweetener in them either ethyl maltol or maltol - if you add a few different concentrates you can end up sweet without even trying
I like 1% Virginia absolute, 0.25% DNB as a solid tobacco base...
TFA DX Caramel is my favourite caramel
