Using the -i option to newfs will not correctly change the inode density for a partition, you will always get the default 2048. The only way to get a higher inode density is to reduce the number of cylinder groups and (!) the number of tracks for that partition. This has the effect of giving you the same number of nodes/cylinder group but each cylinder group is smaller hence you've got more inodes. Of course you sacrifice some space too. The following is what it looked like for us.
