Opinions on it being paired with a 3 syllable last name?
Paired with a short middle name I think it could work. I worked with a boy named [name]Tennyson[/name], he went by [name]Tenny[/name]. I think [name]Tenny[/name] or even [name]Sonny[/name] could work as nice nicknames.
Sounds like it would be too much. I’m a bit of a stickler with the whole syllable-flow thing, though. The only time I’m usually good with a matching number is a 2-2 (first and last).
