If all Nose Cones were balsa, the Shoulder should be turned down to fit inside a Tube Coupler.
The reason I say this is simple, Help Stop Zippering.
Plastic nose cones can not be done to fit inside the BT coupler.
Balsa can be. And should come that way and each kit should have a High Density Coupler for anti zipper effect.
Over the 45 years I've launched LP rockets I've had numberous zippers.
Some with this method would have not happened.
Others, nothing short of a steel ring would stop the zipper.
But, I think it is well advised that ALL manufacturers relate to this problem and do what they can to solve it.
No flight is perfect, well, I could be wrong on that...With that said, I've fallen inches of catching the chute on the end of the launch rod several times.
But my Super Big Bertha, which I fabed to a 2 stage;
It launched great, got about 200 feet off the ground, Shot the D12-0 right at the launch pad, leaned over in a delay of the sustainer...
And ended up with a horizontal trogectory arching into the woods. As the chutes opened into the tree tops, ZIP.
If a tube coupler was in place, and a balsa nose cone instead of a plastic one, I would have less than and inch of zip instead of 8" of zip.
And it would have been saved.
But I should have known better to launch it in 30 mph winds, but as the old school ass I am, nothing will stop me.
Maybe I should make this a Poll?
