I own several domains both hyphenated and non-hyphenated and I see absolutely NO difference in SE placements. With very minor differences either way they seem to perform the same for me. Some of them are 2 words and one is 6 words long. As long as you layout the site with good SEO you should be ok IMHO
And this is from a 73 yr old laymen thats been in the porn biz since the early 90's.
