Wanna improve! Any suggestions?

I live up north in the new york area. I have recently grown five white rhinos and three barneys sweet tooth. I will be harvesting within the next few weeks. Don't get me wrong i am happy with the plants and am happy with dr.chronic bought ten feminized seeds five of each kind and ended up with eight nice plants all five rhinos popped. The thing is i'm looking for the best plants to grow in this area.I want the strongest and easiest to grow outdoors in the crappy conditions we get here i need something weather and mold resistant also. The main thing is i want a very strong strain that will grow good outdoors here. My sweet tooths are nice and might grow them again if i don't find something better the rhinos seemed to be very fussy though had some issues with them. The plants range from six to nine feet tall and will have alot of nice buds on them.I was thinking about going with g13 haze (fem) and vanilla kush (fem) how do you think they would grow up north?I also heard of a strain called timewarp supposedly a very good strain to grow in canada about same conditions we have here anyone know anything about it? Ive googled the best strains in this area and haven't really come up with much so any suggestions would be greatly appreciated.
