one solution to all problems...the speed of this strum can be altered to suite almost any song.. DDUUDU practice just holdin a single chord for about half hour...then start changin chords while playin...use only ur wrist without movin ur forearm too much...u wil gradually start developin ur own strummin patterns once u get the hang of this one..lemme know how it worked so can further provide more info if needed...
