Just wanted to add my 2p to the pile!
Personally I'm looking at grading myself this November, first time I'll have graded in Aikido. I could have graded earlier, but I don't think I would have felt really comfortable trying to grade to 5th kyu until now (more ukemi problems than technique problems). As one of my fellows once said 'Better to be a good example of your current grade, than to merely scrape through a grading.'
At the end of the day your Aikido won't be judged by your rank, but by your demonstrated proficiency...
