Elinchrom RX Style 300 or 600 heads???

Thanks Peter, Yes I understand regarding the 'Lighting Distance' that's why I gave the dimensions of the studio to give an understanding of the working area I will be working in, given the size of the modifiers.

I would be at a minimum of 1m & maximum of 3m away from the subject with key light & the fills would be max 2m away.

I'm not sure I understand you regarding not gaining anything (bar the extra cost) using half power on the 600 with a faster flash duration? Would I not be benefiting if using slower shutter & it freezing any movement giving a sharper image using a faster duration? I'm assuming that the flash duration of the 300@300ws would be the same as the 600@ half power?

I'm pretty sure the 300's would suffice but I just need that definite 'Yes they will' from someone before diving in!

regards
