Also available are replacement bridles for the Djinn, the quad that JB is making. The bridle for this model of quad has a design change from the original Rev bridle that improves some flight characteristics and makes certain tricks and maneuvers easier. It also fits the 1.5 size Revs just like the original. It may be worth a try to see how you like it.
As far as being a fix for beginner blues -- forget it. There's no such thing. You'll get better and have less issues each time you fly, so just hang in there. It will come. We all went through the same stages. Just smile and keep going. After all, you're just flying a kite. Relax. Have fun. Pretty soon you'll be flying well and you won't even know when it happened. Keep watching the tutorials. Rinse. Repeat. Repeat until you're sick of them. Every word you hear, every move you see is Gospel. Tried, tested and proven. You can acquire your own style once you're comfy with the kite.
