My solo was 3 years ago almost to the day, after 22 hours, in an R22. (24th Sept - my mums birthday)!
At the place I trained, NOBODY was allowed to go solo until they had completed at least 20 hours, sort of took the pressure off.
I turned down the chance to solo initially - didn't think I was ready, so I wouldn't go, but went off the very next lesson.
Amazing experience, which really hit home after the landing. Was on cloud 9 for days afterwards
