Need a new lockring

Had a nasty experience today when I managed to strip the thread on my lockring skidding downhill...I'd never had any issue doing this before and I panicked when I thought I'd f*cked my hub!

Fortunately I got it checked out by my LBS and they supplied me with a new one...

I'd rather not have this happen again so was wondering if it my inadequate assembly (I use a chainwhip and lockring tool) or should I invest the extra couple of quid in a DA or similar one?

What lockrings do you recommend?

Cheers

DA lockring solved my slipping problem, definitely worth the extra few quid, been running it for a year or so and no slipping.
