Thing is, other bards I've talked to have tried out both openers and the most common finding they've noticed is that the DoT opener is usually 10 DPS greater than Krietor's. It's a small increase, but still an increase that they've noticed. The parses I've posted do not stray from that trend in any significant way.

Not to besmirch Krietor's opener, but it's spike damage would be better suited for fights that ask for it. The DoT opener would be more for endurance-style fights, which is what the FCoB turns are. It's the latter why I prefer opening with DoTs over Straight Shot and the proof shows.
