Pro 70 work with Radio Slaves?

I am seriously considering purchasing the Pro 70 for studio use. Before doing so I want to make sure this camera will work with a radio slave in the hot shoe (just as I do with my regular EOS bodies w/o additional sync cords). Is there any reason why this wouldn't work?
 
A radio slave will work thru the remote input connector if you have the proper plug...but I have no idea what you would use the hot shoe for.****

Hi, Richard:

You'll need to make sure that the sync polarity of the radio slave receiver is compatible with your Pro70. It should be, if it uses a hot shoe connector. But if the flash doesn't fire, you may need to do some minor surgery on the receiver's sync cord to reverse the polarity. This is the same routine you have to observe with many EOS bodies, especially those with built-in flash units.

And of course you will need to set a manual aperture in the Pro70's aperture-priority mode.

****,

Perhaps I didn't make myself clear. The radio slave transmitter fits directly into the hot shoe of most any camera, which means I DO NOT have to use a sync cord or any further adapters.
I think Chuck answered my question. Thanks.

Richard,

I use Pocket Wizard Plus radio strobes with my Pro-70 all the time. The Plus works fine attached to the hot-shoe of Pro-70. I also use a Nikon AS-15 hot0shoe adapter to sync the Pro-70 with other studio strobes via a PC cord. be aware - some power-pak (and portable) strobes use different sync voltages (and as Westfal notes, polarity). LPA - maker of the Pocket Wizard radio-sync's - also make a low-voltage-trigger box (LVT) that will convert sync voltages. good luck..........
 
Richard, I thought this was answered last month...was the answer incomplete or did you miss it!...the answer was yes.

I received a few emails regarding my post re: Pocket Wizard Plus radio strobes sync used with a Canon Pro-70, so I'll add this clarification: It DOES work...... but you MUST set Pro-70 in aperture-priority mode in "P" mode, and set some aperture OTHER THAN 'AUTO'...... In 'A' mode or 'P' mode with 'AUTO' sperture selected, my Pro70 will not fire ANY external strobe or slave that I've tried. I guess the Pro70 is 'smart' enough to know that the radio slave or an PC adapter is NOT a 220EX or 380EX, and that you must set an aperture manually ...a nice feature, I think!! BTW, ISO rating of 100 in 'large' image mode is fairly accurate for me, but small mode is more like 320-400, IMHO.
On another note, I'd like Chuck Westfall to respond to this observation:

When using Pro70 with non-EX strobes, I typically use exposure compensation in 'P' mode to fine-tune exposures, since Pro70 has no 'in-between' aperture settings - only full f-stops. This DOES work well, however if I take a series of pics with successive increases/decreases of exposure compensation, all the 'file info' data in Acquire module return EXACTLY THE SAME SHUTTER SPEED AND APERTURE VALUES. Just what is getting varied to produce different exposures?..... but as long as something works, don't knock it, right?...I'm a scientist by training and would just like to know!

Hi, Max:

Exposure compensation on the Pro70 is essentially a form of gain adjustment.
