With RIMS you have many options for a non traditional sparge. For myself I have found that I like to add my sparge water at temperature, stir the mash a bit, then recirc for 10 to 15 minutes. After this pump to boil and finish boiling. Over 13 years I have found this to be a good mix of quality, extraction rate, and use of time to keep brew day short.
You could also do many different sparge plans besides what I do. Research here a bit, there are discussions and comments on almost every Conceivable idea from no sparge to very creative and elaborate sparges.
