That's not my area, sorry. I just build whatever's convenient. Probably a bad habit.
Play around with GGDT and see what's best.
Thing- Completion!

Fairly, with some arc. Minor flaws in the cones cause some to curve. I've never weighed them though. The heavier the better. Spike darts work best.

Simply awsome. I like how you set everything up, and that you kept it nice and clean. dont paint it, it looks great the way it is.
