Some nice suggestions!

Add Eyes (e.g. "Evil Eye") to your list alongside raptors, peiste, and eft. I mainly mention them because they are probably the best SP/hr in a grinding PT due to low HP and weak attack, but they aren't found in any large number to suit a full party. Best for solo/duo.

Also, drakes are a higher tier even still. The most i've gotten from a raptor >10+ is 450. I get 600sp from a drake >10+. Though not comfirmed, I suspect there are other mobs on this tier (Goobue and Morbol possibly). But Drakes are all I have solo'd and can confirm. Parties 45+ (maybe even lower) sould be fighting drakes, not raptors, which give much more SP and spawn in high enough numbers for full party.
