You mention three understable flippy drivers, are you using them a lot in tourneys?
It's always going to take a hole or two to get dialed in, if you're throwing stuff that is not forgiving its probably going to hurt a lot in an early round.
I try to start off a tourney with a couple safety drives so to speak, something that is going to go where I want it no matter what.
So a teebird might be shorter than your diamond its also far more likely to not get you in trouble. It should still leave you with par opportunities while giving you time to work out the morning round jitters.
