Yea with Cookie crosses you have to watch out for stress period. I'm running my keeper Platinum Delights now and haven't had any heat problems and she's been perfect. If your gonna run them outside I think they will be fine as they will get accustomed to being outdoors and being in heat.
The SourJack crosses are great from what I'm seeing. I haven't seen much from the old SourJack crosses but these new ones are looking might fine. I'm most certain the Silverback Jack will be released so stay tuned for that one. Attitude has a couple SourJack crosses for sell the old ones Aliens Jackd Up, Dream n Sour, Rappers Delight and Sinfully Sour. New crosses with SourJack will be GG#4, Key Lime Pie, Power Purps, Forum GSC, LVBK, Lemon G13 and White Strawberry
