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.

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.
