High density seeds = hard to repair, perhaps consider alternate node 50mm spacing strings if you want 25mm "spacing" between them.
Strip doesn't like being held under tension, tends to fail from being blown around
Bullet nodes, more expensive?
Moving more towards seeds here, light weight, smaller, cheaper, found some even brighter than 2811 nodes too with RGBW. Shouldn't catch the wind so much and act like a parachute.
I currently have a 360 deg, 32 string of 50 10cm spacing bullets
I am not satisfied with the density, so I am changing to 180 Degree 32 string of 100 with 5cm spacing evo's
From my experience of a seed pixel mega tree; great if you like the look, cost savings and small storage space.
But bad if you want robust and strong pixel strands and pixels to last.
