Now Tungsten density = 19.3g/cm^3.
All "tungsten" beads must be alloyed - max alloy density I know about is around 18g/cm^3.
The best "tungsten" beads have the highest density, as well as the smallest PRACTICAL slot/hole (width & shape)m as well as the least amount of countersink (for beads with a hole, not a slot).
To be honest, most tungsten beads come from a very limited amount of suppliers, mostly in China, and thus most will be similar in tungsten %.
That said, Competition Tungsten is a brand out of Europe, which claims a greater tungsten %, and thus density.
From my testing, using an accurate scale, this is around 8-10% more mass for the same size slotted bead. Some of this is probably down to smaller slots/holes. Their countersunk are closer to 2-5% heavier, since they have quite a large "countersunk" cutout. Whether this ~5-10% is enough to go a bead size smaller is debatable. Slimmer flies, thinner hooks & less bulk on the fly is likely to have a greater effect than 5-10% heavier bead.
