I like LA Confidential too, and especially one of it's kids - it went by Lohan / Confidential Wreck (LA Confidential x Trainwreck). DNA has something called Training Day, which seems to be the same cross.
The Darkstar I had was the most narcotic strain I've tried. It was completely insomnia negating and was good in the pain relief department. I grew some of Swami Organic Seed's
Mazar-I-Sharif x
Pakistani Chitral Kush, thinking it would be a great substitute for Darkstar, but no. It was a pretty plant with great terps, but while nice it hit me more as a sativa. I never know how a strain will hit me...
