Chapter, this options puts you in a scary "blue" zone, when you use the HCA tool, giving you a 5.6, when you want to be under 2.
 
Hi Chapter

Very steep pavilion angle which is risky for light leakage and colour entrapment, the long lower girdle facets might help a bit but still that pavilion angle could cause problems - do you have any others in mind?
 
no good.
 
The stone will probably behave like a steep/deep because of the pavilion.
More than 41.0 pavilion is asking for trouble.
