Since I was a kid I was told I was "double jointed". With my fingers I can hold them straight (joints locked straight) and and flex just my last knuckle (so my finger tips are pointing basically towards the ground). For climbing this makes about a perfect open handed hook, but it feels REALLY weak. Should I work on making this stronger or should I concentrate on keeping a little bend in all of my knuckles?
I know I don't really have extra joints by the way....
Thanks in advance.
