As SV provides you with tenderness once you understand times/temps,
no need for tenderloin, a less flavorful cut than the larger loin.
and a few more $$$$$
glad you've Seen the Light !
BTW 'less time' in the SV world should only refer to 'mealy-ness' not 'done-ness'
once your 'bag' gets to its iso-thernal state, additional time in The Bath is for connective tissue breakdown
I personally am of the 'Target-Temp' school of SV, not the 'Initial-Overshoot' school, where your water bath is a few degrees above
your target temp. but to each their own.
looking forward to your Venison Studies.
