You still running the Rastas or have you effed around with other fins?6-4 Bullet Twin has been way more of an instant success than the Twinsman was for me. Really fun at multiple different spots in varying conditions so far. So much glide and speed up front and the thin rails hold through everything. It's not as much of a pivotal ride as the twinsman but it will still go vertical with good technique and timing. I've had some very fun fin drifting turns and end section bashes but the best sensation so far has been entering a steep section with speed, putting it on rail and pushing through a carve. Fark me what a good feeling. 4 sessions down in fairly marginal surf. Can't wait to get it in some real waves.
