Choosing an Angel for my Reef

[straightrazorguy]

I want one more fish for my 3 ft cube (150 gal). It is a mixed reef (SPS, LPS, a few zoas, mushrooms and a gorg). The tank is fully cycled, has a 55 gal refugium full of critters, and is almost fully stocked up with fish. I would like to add a medium-sized angel or a pair. By medium I mean under 6 inches fully grown. I know angels are hit and miss when it comes to corals. I do feed my fish 3 times a day and am willing to take a chance. Some of the angels I am considering are:
- Venustus angel
- Multibar angel (preferably a pair)
- Potter's angel
- Bicolour angel
- Regal angel

I'm looking for advice from experienced reefers. Which one would you choose from this list? Any suggestions that's not on my list?
