Those new trainers look like they are really sweet. The bendz wouldn't help you as much in the space you have. Those are much better for sure. I got totally lucky that I looked those up when we were discussing this last fall.
With the right strain in the right conditions, using those trainers, I can get one plant to fill my entire tent. I have done that a couple times if I know I will get a monster. So far only one strain, Auto Ultimate from DP actually filled up the tent, back when I was running a 600w hps. She grew to around 750 grams or so, I didn't have scales at that time, but she was a monster. Decent smoke too, but not quite as tasty as the stuff I grow now.
