As you are looking for suggestions, I would add the Air Tight Supreme to your list. It was developed on an SME V arm like you own and the match is superb. It has great speed, detail and dynamics and its sense of tone is rich and dense. It is an extraordinary cartridge. You may want to contact Albert Porter who has compared the Atlas to the Supreme and has written about them on his system page.
Have fun trying to decide which is best in your system.
