Benefits/Drawbacks of Series Play Calling?

I'm going into my second year as an offensive coordinator and considering changing my playcalling to a "series" concept, much like many Double and Single Wing teams run. Whereas I played under and so far have coached with a traditional playcalling system (first number dictates the back receiving the ball, second number dictates the hole), I wanted to know the benefits/drawbacks of a series system. We are a Pro Formation splitback veer team and, because both backs are the same in a splitback system, I think it may be unnecessary to designate the ballcarrier. I also think it could be beneficial to the offensive line because they just need to wrap their heads around one playcalling series at a time in practice. I also like the idea of using the series to organize summer practices, where one series can be installed at a time. The series I was thinking was as follows:

"10" Mid-line/Outside Veer
"20" Power/Dive/Wedge
"30" Guard Pulls (ie trap/belly/counter)
"50" 5 Step Concept Passing
"60" 3 Step Drop
"70" Play-action (Waggle, Veer/Dive Pass)
Richie/Louie - Sprint out (This is what we call our roll-out game, I see no reason to change)

Do any coaches run split-back/wishbone/flexbone/I option as a series? What are the benefits/drawbacks? Do you think it would be beneficial to make the switch?
