Pickup for Martin DSS-15M

[CEB]

I need a pickup for my Martin DSS-15M. It's an all mahogany sloped shoulder dreadnaught. I like the natural sound of the guitar. I have a Fishman Platinum Pro preamp I can use. I'm thinking about the K&K 3 head transducer.

Are there any better recommendations. I will use this in both acoustic and electric band settings.

Thanks
