The Next Regionals - Considerations

My playtesting seems to be revealing more negatives than positives as time progresses. Perhaps it's because I'm more pessimistic by nature, I don't know. However, these considerations obviously need to be strictly address before selecting a deck. I will go into these negative considerations deck by deck

Mermails:

First of all, I haven't chosen a variant yet. This is insanely problematic, because time is running out. I want to swing towards the mono-Mermail version, but it requires 3 Abyssmegalo for consistency, and I only have 2. Also, I don't have an Abyssleed yet, but I think I can get one before the event.

In regards to its match-ups, it's common knowledge this deck loses to Macro. I've also discovered, the hard way, how badly Shock Master damages this deck. Since I play minimal defensive spell and traps, I find myself starring down a Shock Master until all of it's materials are gone. At that point, it's usually too late to make a comeback.

Fire Fists:

The obvious issue is that the deck might not be available to me, due to complete crap. I'm also not sold on a variant for this deck either. I want to play Vorse Raiders, because of DDV, but then I have to adjust my deck slightly to support that.

Otherwise, this deck faces a bad matchup to Macro. It also doesn't have the best matchup against Mermails. Other than that, this deck is strong and potent, doesn't require that much thought, and can sack really hard sometimes...

Dark Worlds:

Speaking of decks that sack really hard, I've chosen my template for this deck, and it's of original design. Now I just have to work out the kinks and weaknesses. I'm still testing secret tech cards, and my opinion on how many spots in the deck they should take up is still unknown.

This deck auto-loses to Macro. In my opinion, it has a worse match-up against Macro then any of the above decks. Also, the deck is really shitty when I don't open with a discard outlet (like half the time...). This deck also has a difficult with Shock Master, but since Grapha's special summon condition gets around Shock Master, it's not the end of world, right way anyway.

Dino Rabbits:

This is now the final deck I'm considering. No matter what, my version will be playing Macro, because it's strong right now. I'm contemplating between tech cards though, and I haven't tested these tech cards enough to be sold on them yet.

My only quarrel with the deck is that I open with Normal monsters frequently, usually multiples. However, the deck does open broken sometimes, which is unavoidable.

In conclusion, I've managed to knock down my decks to choose from to 4. I've discussed my issues I encounter with these decks, and I have just over 120 hours left to make a decision. Please respond with your advice; it is greatly appreciated.
