'Good Merges', Skills of the Good Merge Flesh Form bug? Options

[Apathy]

Ok, MITS says that good merge flesh forms (GMFF) retain the knowledge and memories of the original host, and can use these memories to pass as the original character.

1) Would this GMFF use the mental attributes of the host or retain those of the occupying spirit? If the host had charisma 6, and the occupying spirit has charisma 1 (or vice versa), they'd have a hard time appearing the same.

2) In addition to possessing the knowledge skills, would the GMFF have the same active skills as the host? What about if the host had Conjuring? (MITS says only Bug Mothers get conjuring.)

3) What about a good merge with a paracritter? Would it then retain it's critter powers? (This could get really nasty, investing kennels full of bogies, etc, with high-force Flesh Forms as good merges.)

4) MITS says that GMFF's get Masking, and the Spirit Power Masking uses Force in place of Magic, and Spirit Energy in place of initiate grade (I think, don't have it with me right now.) But only free spirits and bug mothers have spirit energy. What would be the rules for penetrating the masking of the spirit which has an effective initiate rating of 0?
