Is it acceptable to use 6.8uH with the LT3494?

Category: Choose a category
Product Number: LT3494

I plan to use the LT3494 with an output voltage of 15v and maximum output current of 40mA.  I'm looking to select the smallest inductor possible and I'm planning on using the XFL2006 series because they provide enough current capability.   Regarding the inductance value, the datasheet recommends 15uH, but LTspice simulations show better spurious performance with a 6.8uH inductor.  Are there any drawbacks with using the 6.8uH inductor?
