I don't quite understand....  From man 8 newfs:

	.B \-i number of bytes per inode
	This specifies the density of inodes in the file system.
	The default is to create an inode for each 2048 bytes of data space.
	If fewer inodes are desired, a larger number should be used;
	to create more inodes a smaller number should be given.

If you have one inode per 2K of data space, then it doesn't matter
how many blocks/cyl-group; more blocks just means more inodes.  So
how does having rp07s make any difference?
