On my first RV-3, VG's were placed in pairs about 6" apart and 6" aft of leading edge forward of the ailerons.  Did this to improve stability through the stall.  It slowed the stall about 4 mph as well.  Have been going to play with VG's on the current 3 to reduce the sink rate at low approach speeds but have not been able to find the small T bar as the plastic angle used previously was not "flyin proof".   
 
Hi Rich,  
 
Very interesting about the VG's.  I've hear others talk about using these to reduce stall speed, but always wondered how much of that was true.  Try to get all the details worked out by the time I need it :-)
 
As for T bar, is this what you mean-  http://snipurl.com/1wndd  (formerly about a 15 inch long URL from McMaster Carr)   
 
 When does the kit start arriving? 
 
Since I'm not a complete masochist, I ordered the quickbuild wing option.  As I understand it, the empennage will arrive in just a couple weeks, and the standard wing and fuselage kits take 6-8 weeks.  When the standard kits are ready, they will send me the fuselage kit, including the fuselage parts that are normally included in the wing kit.  They will then send the wing kit to their QB folks in the Philippines, and I won't get the nearly completed wings back for 4-5 months.  My goal will be to try to have the fuselage ready to mate the wings by the time they return, but that's pretty optimistic for a non-pre-punched kit.
