Anything worth doing, is worth overdoing.
If you truly want to be discrete I would suggest pressing your nugs into rosin with a Dabpress, then you can carry a more compact setup that looks like any ordinary ecig. That's discrete.
+1 I had very good discretion using rosin in a Fury 2, and will still have the F2 in the rotation. However, I have been fucking around with the Boundless Terp pen for the last few weeks and have loved the ease of use and discretion. A little rosin on the tip, put the cap on and you're loaded and ready to puff. You can carry a little dab jar, touch the pen tip into your jar and you're ready to go again.
If you don't go crazy, you don't need to up your tolerance. You can just take a few small hits to equal the higher number of hits you would take on flower herb. That said, you do need to monitor and keep yourself at a tolerance you're comfortable with. It can get away from you if you're not careful.Homemade rosin appeals to me as someone just along for the ride on this thread. Wouldn't daily concentrate use level up my tolerance though?
To me, the easiest was the ccell cart, but I'm off cartridges for the time being.
