Longboard bushings, want to carve better. new bushings or gullwing sidewinder?

The sidewinders are actually very fun. I have ridden them before and love how hard you can carve on them. If you are willing to purchase them, I would say go for it. They are a great reliable truck specifically designed for carving. You will get much more out of them than just switching bushings. Also, have you ever tried the trucks that are equipped on original longboards? You can carve extremely well on them because they use springs instead of bushings. I personally find them a little too loose, but they will carve as hard as you push them.
