There are a few pieces to this, so first question is have you done any of the schools, levels 1-3? I only ask to know if I can refer to something that you might have been trained on.
The next thing, both Stomp Grip and Tech Spec were mentioned: they are a great aid, and make the job of holding on to the bike a lot easier.
One question about what you posted: you said you can't get a grip o the tank with your feet--what are you trying to do now, how are you attempting to hold on to the bike under braking?

I've done twice the 0-300(0300 is a Greek motorcycle magazine) riding school which is more or less like CSS level 1. Here at Greece we call it pre-level and you can learn about gyroscopic effect, throttle control, braking, body position and concatenation on your moves.
All these are being teached in an one day school of 4 theory and 4 practice sessions.
Regarding your second question, alternatively, I've tried to get in turning position earlier and use the inside of my outside leg as a stopper at the back of the tank.
This did not seem to help a lot, especially while braking from high speeds as leather suits have elastic pieces at the adductor area and you cant get a good grip.
The second thing that I've tried, is pressing on the pegs so much that my butt is not touching the saddle and keeping my elbows a little more bended(not that easy cause I am very short).
This one seemed to help things, but I don't know if I can do it consecutively during a track day session.
PS
Sorry for my Greeklish English. Hope you can understand what I am trying to say.
