thanks for your quick answer Maxwel,
the vest is new to me, i bought it second hand which was declared as goofy, just like me. so i didn't change sides or anything. your lead is a good tip, i'm finding mine with a pretty straight block in the back, not sure if this old version of the harness works with a crossover block, but logically it should do just that, changing the angle of the socket block so the upper end of the block moves away from the vest while the lower part moves towards it, am i right?
since this is a 3" dropdown arm there's little use in switching sides no matter what block is used in the back?
thanks for your help!
