Just found this on the Taylor web site...
http://www.taylorguitars.com/guitars/re ... .html#faq9What kind of strings should I use on my Baby Taylor?
We install light-gauge Elixir NANOWEB strings (.012 on high E) on Baby Taylors. We recommend that you stick with lights when you replace them, and keep the Baby in standard tuning. After the Baby was introduced, we said that it would be okay to use F# tuning on the Baby, and that you could even use medium-gauge strings if you didn't venture above standard tuning. Well, our ever-vigilant repair guys, who are the ultimate judges of what works and doesn't work on our guitars, finally prevailed in convincing us that tuning a Baby higher than standard and/or using anything but light-gauge strings puts too much tension on the top of the guitar. Putting mediums on a Baby at standard pitch exerts about the same tension as lights exert in F# tuning, so neither is advisable. When there's too much "pull" on a Baby, the intonation and one's ability to keep them in tune become problematic.
