I totally understand why a guitarist would use such a tuning. But why a bass player? He won't be playing open power chords...will he? The same notes are available, he just has to reach them in an unorthodox fashion, which would make study bloody hard work.[/quote]

If you really need the low C# then either drop tune C#F#BE (or even BEAD) or get a five string. Otherwise you're just making it harder for yourself with no clear advantage.
