I'm very much in the pro-strap, two strap button camp. I have strap buttons (or pick-ups) on the tail block and heel of all my ukuleles. I play standing up at times, and I find I have better control to move around the fret board with a strap whether sitting or standing. I debated and procrastinated for awhile about putting buttons on my KoAloha special issue LN soprano. I picked out some Waverly tortoise shell buttons that look good on it. Something a little nicer than the plain metal ones. I have my local acoustic guitar & uke shop install all my strap buttons, unless I have them pre-installed by HMS, Uke Republic, etc. I love Sherrins Threads 1 inch straps. I have a different pattern strap for each uke that matches the uke's personality or look. I contacted Sherrin directly to order a strap that was out of stock, and she helped me to get it.....a strap with blackbirds on it for my new Blackbird Clara.
