Plenum vs. Sand for large remote DSB?

Am finishing a build on a large (~1500G) reef system which will incorporate a 150G, 50" deep remote DSB. Am considering whether to do this as a plenum or as a homogeneous sand bed. Recommendations? If one type of sand only, any recs regarding type/density?
 
I've done both plenums and DSB's without plenum's. I wouldn't bother with a plenum ;) Just go for a nice thick DSB with fine grade arragonite sand.
