Quoted from Lhyrgoif:but the new springs were stiffer than the original ones and the eyes refused to work properly until I put back the old springs again. Maybe they could have worked if I changed the head coils to new (stronger?) ones too.
Same problem here. I ordered from two different shops in Germany and the eyes didn’t work well. I even changed the coils but no improvement.
The old original springs are easier to compress.
