BTL's what's the difference?

[BUSABAZZ]

So what exactly is the difference between a standard back torque limiter and a welded one?
I have a welded one but have been told it's not so good for me since I only do twisty hills or highway riding.
If that be the case would I be better off replacing the welded one with a standard BTL and have the "slipper clutch"?

I'd really appreciate your input.

Cheers,

Bazz.
