Arkayem, you make good points, all specifically correct.
Generally my points were stated to encourage the OP to get the flash off the camera as easily as possible and start enjoying the world of OCF.
Whether TTL or TTL-BL, either will give better results than on camera flash, when used off camera. Lets encourage starting!
CLS is discussed everywhere, I believe your reference to AWL is the first I have read in a forum, I am sure it is somewhere, just not frequently mentioned. I have the NikonianPress book on the Creative Light System. CLS is in the index, AWL is not. Again, I was just hoping to direct an on-camera flash user to try off camera flash.
And so on.............
In conclusion to the OP, try getting the flash off the camera, no matter which method you use, and watch the approval increase when people look at the results of your new technique!
