Proto/north star and counter attack

I got my mystery bag with my counter attack and was wondering if it was anything like the protostar or norhtstar. The idea behind them looks kinda the same, but I only have the counter attack so I have no idea.

I have all three and proto/north are similar but nothing like the counter attack. Counter attack has a shape closer to a PGM.

I think the only thing that the protostar/northstar have in common with the Counter Attack is the metal weight ring. The counter attack’s shape looks like the exact same mold as the PGM… The weight is also more like the Northstar at 69g. Is it a fun throw? I’ve always thought that the PGM mold was very comfortable to hold.

Oh okay thanks.
