Record weights

Shun Mook is the best record weight it does cost to much also 3 lbs is to much for the bearing on many tables.

 It all depends on the table. Clearaudio makes a clamp for the especially for the Concept. They also have the Twister that would work well with the Concept.

 I own a Clearaudio Innovvation Wood and use the VPI record weight. But my guess is that it may be a bit heavy for the Concept.

10oz is plenty enough. i use DIY 'pancakes' from TVC-like material 10..12oz I cut on my dad's lathe.
3lb is overovertheoverkill.
why stress the label so it stresses the rest of surface? 

If you want to go lite, try a Starsound Platter Ground(200gm).  It's not so much a record weight as (in theory) a means to redirect spurious vibrational energy out of the LP.  I also have a Stillpoints LPI(around 1.5lbs) that works well.  I plan to compare the two across several tonearm and cartridge combos and post results.
