We call it backstrap in the UK

I could never get my backstrap joints to be tight enough, always a little saggy. Still very smokable but around the roach would sag and bend

Takes a little practice to perfect, even then we're bound to screw something up, we're only human.
Easy fix for when it sags at the roach is to just help the roach up the joint slightly. You'll have a bit more stability at the base.

I just use raw blacks now and rip it to width first. Same thing 😂

First I heard it called backstrap, we call it back-rolling down this way.

What are the benefits to rolling like this? Less paper?

Aye that’s the only benefit mate and i ain’t got time to piss about rolling a joint backwards to lose a fannies hair of paper 😂

They tend too smoke nicer and you taste more of the bud. Can even slightly alter ash appearance. Fun fact it doesn't actually take any longer than rolling the standard way... 🤣
