Bob, this is the helmet I'm using, I'm pretty sure I've got travel rate and consistency issues but I'm not sure the helmets helping as I'm still struggling with seeing the joint, will give it a try with scribing and chalking as dualist mentioned when I get set up for a next play
Cant do much more now as I've run out of tube, have to go scrounging round the industrial estates
In the meantime I'l get my eyes tested, I should get that up to date regardless.
