All black or white ABS will be standard. Semi-hollow with consistent wall thickness. Aluminum tip 25-35mm long. Nosecone = 29mm diameter.
If you had these following options, what would it be?
4.5:1? 5:1? 5.5:1? 6:1? (Exposed Length)
Conical, Ogive, or Von K profile?
Bay, or no-bay? (tapered sled with slot in it for battery use)
Closed eye-bolt, or U-bolt?
The effort for a bay design will be more, as it needs either a turned aluminum or a solid dark-gray PVC bulkhead closure, that is countersunk drilled around the outside of the face for screws into the NC shoulder. Price would have to reflect that extra material/labor. Please consider this.
EDIT:
The results are in. Empirical data shows the Von Karman simply blowing the other shapes away in aerodynamics, at areas especially near M=1.25 & M=1.8+. All around less drag everywhere it appears, and the best nose to get near or past mach 2. It looks like that option, will be a given:
