When I mix my Jack Herer with cbd bud it gets stronger. It actually reminds me of the good brick weed we used to get. Very hard to develop any tolerance to, it works every time.
I have another cbd plant Island Dream with 6% thc, 8% cbd but large amounts of terpenes, tastes like spices and incense. Everybody loves it, my only complaint is that it is easy to build a tolerance too.
