I keep reading about the neck dive phobia. What is worse, you drop the neck drops you are playing and the uke is still hanging on your shoulders on the strap, or the the sickening noise a uke makes when it bounces on concrete or a hard wood floor because you did not fit a strap? If you have problems which cause you to drop the neck, you probably need a strap more to stop the uke hitting the floor than you need it for the music.
We are talking about a $200 plastic uke, not a Kamaka or Kanilea. If you want to be real world, you are going to take your plastic uke on some adventures outside your house, without a heavy case, and you are going to need a strap to carry it while you are hiking or walking or riding your bicycle etc.. Head drop and ease of playing are only half the issues you need to think about for a strap on an OU. When you go out to a venue for a jam or festival or fun don't really need to put the uke in a case while you have lunch or a coffee, you can keep it safe and secure on your shoulders, hands free without lugging a case. Then when you finally sit down to drink the coffee, you have your uke right there ready to play a tune in between mouthfuls of coffee and chocolate cake (which you can also eat with an OU because you can hose it off when you get home). Fitting a strap to your OU is going to increase the availability for playing and may change your entire ukulele life.
