    These are 4.5g, 6.2 seems heavy for a titanium retainer, even Riva ones are in the 4.x range I believe.

    There is a lot of pushing down on the retainers at 8000+RPMs. I believe that the supertech titanium retainers are also in the 6 gram range. I wouldn't trust anything lighter then 6 grams in titanium when the stock steel are in the 11 gram range. It may be okay for a stock application but I wouldn't trust that light of a retainer in a modified machine spinning more then 8200 RPMs.

    They look exactly like a WSM copy with titanium stamped on them. I believe Supertechs retainers are also in the 6 gram range..

    I have a set of supertechs but they are installed. They sure look heavier then the WSM titanium retainers. The top shows plenty of titanium bulk like the aquasport..
