Hi learned Flash guru's.

As a relative beginner in off camera flash, I've got a few questions that some of you far more experienced might know the answer to.

I have 2 SB700's, an SU800 commander and a D700. I'm fine with using these optically, but it's problematic in bright sun or at longer than the 10mtrs recommended with the line of sight issues.

Hence my desire to go to the radio trigger units. As my SB700's dont have a sync port, I've researched that I need to buy some PC adaptors with a sync cable, mount them under my SB700's, connect the other ends to the Pocket wizards in order for this to work.

So my questions are:

Do I get rid of the SU800 as this is redundant, if I buy the PW kit?
Will I be only able to use Manual Flash as I won't have the TTL option with this set up?
Should I sell both SB700's and get another Nikon flash that offers better/easier connectivity options with the PW's?
Can I get away with buying used PW II transmitter/receivers?
Does the Mini TT1 and Flext TT5 work with my current SB700's and how would I use the sync cable in this set up?

Hope someone out there can give me their sage advice.

Cheers, Russell
