I've gone back to the many different methods i used to use and catch plenty on before i started using the booms,it's just i was wondering if it was me or a design fault on the booms as they seem like a good idea but just don't seem to work so well(for me).Yeah at times i do use lighter hook lengths 12-10 ,10-8 ,8-6 ,6-5 fluoro carbon etc ,but at times it's just not needed to use a hook length ,and to be honest i haven't been snapt of for many of year (while specimen hunting) thats not to say i wont be soon.Just think over the years I've come to know when to use lighter hook links etc.Don't feel moulding lead around the swivel is a safe method tho as that's basically fishing a bolt rig, IMHO.rig tubing does the similar desired effect to as the lead imho, witch i slide over my swivels etc and weighs a considerable amount less imho.
