Chromoly will only save seight if it allows you to use thinner wall tubing, the material it's self weighs the same. If you have any doubts about your welding abilities, 1018 DOM steel is more forgiving. 4130 is prone to brittleness in the HAZ if welded with excessive heat. Do some Google searches on the subject.
