I never did a det in the VTs myself but had some bros who did (I think to Havasu?), everyone agreed it was gouge. Flew their asses off, had fun after hours, got to get to know the IPs on a more informal basis over beers in the evenings. Personally I would much rather have done that than sit around the student RR for a month waiting out the crap Panhandle March weather trying to get my VNAVs done.
