Nicholas or Luke. If you end up using Steven I prefer it spelled with a V. Every Stephen I have ever know hated being teased with "Steph-en" or "Steph-anie"
I was reading your list thinking a know a few people with each of these names--not bad names but common. Then I read Simon, I never hear Simon and I like the name a lot. I vote that 100%, underused and great--go SIMON!
