Tooooooo subjective.....You may hate my choice. Depends how long someone has been smoking a pipe. Many people really enjoy half and half, I like the taste but that one seems to always bite and I've been smoking a pipe for decades.
Lane has a tobacco I had for the first time last night literally called burley without a bite. It has a surprisingly low score on TR for how inoffensive it is. Its the definition of an all day smoke: light, pleasant, slightly sweet. Also drier tobacco bites me a lot less.
There’s no one answer to this question. A blend will bite one person and not another.
I enjoy matured red Virginias and others experience a lot of pain with them. Same goes for burley blends.
Right now I’m enjoying some SWRA, mellow nutty and flavorful.
And I enjoy McClelland 40th.
No bite at all?

You might die of boredom, but it won’t bite.
Otherwise you are bound to your mouth chemistry. I burn with Virginias. I’ve learned to smoke slowly enough that I can enjoy them, but it takes work. I can smoke the harshest Burley with much less care. Other folks are exactly the opposite.
