Draglite locking lugs?

Looking thru summit to get some 15x8 4.5-BS for my Duster and came to the lugs for this set up(1/2 x20 RH).
I was wondering what most of you were using for locking lugs?

Ill be getting the open racing lugs(http://www.summitracing.com/parts/wld-601-1426) for the majority of the studs, but I would like to keep the wheels on the car and get some locking lugs for the remaining four studs.

Only open locking I could find: http://www.summitracing.com/parts/mcg-24010/overview/

Close length/diameter but closed: http://www.summitracing.com/parts/mcg-23181/overview/
