First, all our packages are priced according to the same formula: Buy one light and get 5% off any accessories, two lights = 10% accessory discount, 3 lights = 15%, four lights or more = 20% accessory discount. Vagabonds are not considered as accessories. This info is detailed on our website. See
http://www.paulcbuff.com/packages.phpSo you can build any package you want and the shopping cart will calculate the same discount as you would get when ordering the same items as contained in a "kit" such as the Genius Kit or any other.
So, yes, you can individually put the items in the Genius Kit in your cart, with any changes you want, and the discounts will end up the same. As you change items, the cart will automatically calculate the discounts - before you commit and send the order.
As for your question regarding two Omnis instead of two PLMs, yes, you can easily do that. But my suggestion would be one PLM and one Omni. Also, if you buy lights and accessories and later decide you want another accessory(s) within 60 days, you can still get the discount on added accessories.
Were it me, I would choose the 64" PLM Soft Silver with 8mm shaft instead of the Extreme Silver with speedring mount. I think you'll find it more versatile, easier to use, and cheaper.
You will find having the two different types of modifiers more useful than having two of the same modifier type . . . each has it's best-use and you will likely end up using both together - say one for main light and one for fill light, etc.
