Trackjack and CBJNGood or bad?

I would like to know what pro counters think of these,obviously there are handy for a small time counter who happens to be in such and such a city or going to vegas for a bit.
But what if you happen onto a game with great pen and good rules wouldnt you get a bit angry if it came up CBJN or TJ,the place would soon be swarming with counters and eventually die.
Also cant casino bosses get these and straight away see if their game is going to attract counters and then make it worse?
Are CBJN and TJ counter productive to pro counters?
