What's the fastest way to get these? Is it still desynthing Artisan Tools?

Also is it better to get Artisan's Needle or 2x Artisan's Spectacles? ie. Quality vs. Quantity, I know Needle has a chance to give up to 3x MCD, but I could get 2 Spectacles instead which might net steadier results.

Working on leveling my BSM desynth as well.
