I have a dilemma,.
at the moment I have a Canon 580 ex 2 flash .I can get it off camera with extension cord and do have some idea re bounce effects .

Now do I get a second gun 420 and benefit from multi flash and wireless capabilities or do I go for a basic studio kit .

I am not particularly after equipment recommendations it's more a case of asking those with studio type lighting what are the pro's and cons .

I have read a lot but want to invest wisely.
