I just need to find some tests to tell me which is "better".

1) there are around six (6) different types of VGs in existence.
2) of those six, there would be applications for:
* sub-boundary layer thickness VGs
* equa- boundary layer thickness VGs
* and extra- boundary layer thickness VGs
3) 'solutions' require empirical testing, they cannot be mathematically modeled.
Each of all VGs, under at least the three height categories would need to be investigated.
4) Zero-yaw and crosswind condition testing would be mandatory.
5) optimum number of VG testing is mandatory
6) optimum placement of VG testing is mandatory
7) all the testing would require a laboratory environment, with a single variable allowed, the VGs themselves.
Only under these conditions would data have any scientific merit.
