I bought a Spirit by Steinberger GT Pro and thought I'd may as well buy an extra set of strings at the same time.
The GT Pro came supplied with a ser of .010's and I've always used .009's. String gauge changes on regular tremolo guitars are a real pain, to say the least! With the GT Pro I'd changed the whole set, adjusted the tremolo tension and stretched the strings ready to play within 5 minutes. Great strings, good tone and long life (I'm normally quite heavy handed and go through strings quickly, but these last a but longer than my regular branded strings on my other guitars!). Well worth getting these than buying a string adapter and using "regular" strings!
