Thanks for the replies, guys! Actually I was really just looking to get educated on the strings. Mainly the difference between the calibrated and non-calibrated Steinbergers.
I am able to get the d-string tuned up ok. It just seems tighter than the others and I was just trying to attribute it to the use of an off-brand (D'addarios?).
Michael, I'm on a business trip to Dallas, TX and brought the Spirit along so I could practice at night when I get off of work. It worked out great as a carry-on. The security gate at the airport looked closely at my laptop but didn't even open the gig bag to look at the bass!
