Even though the D70 is compatible with the CLS(Nikon's Creative Lighting System) my friend and I ( who also has the same 2 cameras and speedlightslways use this setting when we shoot in the A or S mode. Bottom line: if it works-do it.
By the way--another reason to buy the D70 over the D100, the D70 is compatible with CLS-though this will never come close to using a professional studio lighting system.
Keep shooting

I have already used the D70 with a professional lighting system and the results were great. I used the SB800 on manual mode to trigger the slaves.

My (French) D70 manual says (on page 94) says that i-TTL BBL mode is for when you want a "natural" effect with ambient light. The "standard" i-TTL mode is for when you want to make the main subject take prominence over the background or you want to use exposure correction.

I'll keep on working at it.
