You are right - they are heavy wire.
Have never really considered the appearance of the hooks.
I just thought "the stronger, the better".
I will definately see if I can acquire som TMC's.
I also bought a pack of Owner hooks the other day, which seems nice as well thou also rather heavy.
Below owner versus prince, both size 4.
The Owner are very expensive in Denmark - ~ 7USD for 7 pieces
I get 10 Princes for the same price.
