thanks for the welcome and the quick replies!
im thinking of getting the bluefin as its one of the cheaper flashes around (in Oz!!)
if i want to go straight to Stage 2, what would be the procedure for it?
fit s1, then catless DP, then tell them about s2?
or
fit catless DP, then ask for s2 straight away?
does S2 get rid of CEL if a catless DP is used?
