Let me throw in my $.02 on the DLE 30. I have a Hangar 9 Edge 540 78" and a Lanier stinger 120 both with DLE 30s. Each weigh a touch over 13LB. The 30s with a Xoar 19x8 have impressive unlimited vertical. The edge will do decent 3d the stinger wont but it wasn't made to 3d.

As many have stated 13LBS. is the upper limit for 3D on a DLE 30, but they will sport fly 15 LBS very well I am sure.
