Subloads absolutely suck, I avoid them unless there is no other way (spare 40mm, multiple layers of extra gear, etc) and only lightweight stuff.
For competition the kydex models work best for most. If you go to a warbelt, a couple HSGI Tacos and a good retention type holster will work well.
"And Shepherds we shall be. For thee, my Lord for thee. Power hath descended forth from thy hand, that our feet may swiftly carry out thy command. So we shall flow a river forth to thee and teeming with souls shall it ever be. In nomine Patris, et fili, et Spiritus Sancti. Amen."
