Im not exactly sure about how thesell match up, so it may end up a bit different. But...

Heat A
Black Panther Queen
Cosmic Thunder 2
Judo Chop!
Natural Selection
S.D. IV
Yet Another Cut Above The Rest

To me, this seems like an excellent heat. We have a powerful disc, with YACATR. S.D. IV provides another semi-powerful cutter. Black Panther has its coolio hammer. And Cosmic Thunder has a pretty cool flipper. Judo Chop! and Natural Selection dont look all that good to me though... The Splinter design was semi-good, yet it had a lack of power. Mostly because stronger armor was usually put on the sides than the top. It doesnt seem the best to me. Natural selection... well it wont do good against the discs, seeing as it has weak armor. Also its slow self-righter and speed make it weak to Cosmic Thunder... It probably wont do too well in this heat.

Between YACATR, S.D. IV and Cosmic Thunder... hmm... S.D. IV could probably take out Cosmic Thunder, maybe. Then again, CT has good armor and having no undercutter on SD will hinder it. Though either one could lose or win against YACATR.

Heat B
Flank Attack
Love Bite V2.0
Mega Masher 2
SOR 5.0
Storm 2
Tengu VII

Hmm... Storm 2 has a good chance here. SOR is pretty slow, so thatll hinder it. Tengu VII could do well if it didnt go up against anyone with good armor like Storm 2. Flank Attack could also stop Tengu in his jaws, and can really use that plow here to get under the likes of low robots and get them in his jaws. Love Bite seems a little too fast, while Mega Masher seems a little too slow.

Heat C
Disco 5
Going Crunch
Leprosy Infection
Omniforce
Shovearound 2
Whirligig 4.0

Dun care this isnt my heat =D
If I had to put my money on two robots though, it would have to be Shoveareound 2 and Whirligig.

Heat D
Clawdius Decimus Murderous
GeForce 4.0
Kali
Panicking
SUNCUST
The Windmill

I honestly think this is the perfect heat for The Windmill. SUNCUST is really boxy, good hits for that bar. Panicking cant do much to The Windmill without being hit. Kali has those jucy wheels protected only bar a small wheel guard bar. GeForce might prove to be some trouble, but if I can hit those pistons all the better. And Clawdius has some nice places I can hit.

Heat E
Axe-O-Lotl
Cyberdemon
Malaria
Psyclonised
Slammer V
Wind Chaser

Thisll be hard, I think Slammer V has a good chacne.

Heat F
13Black
Achilles
Cacodemon
Killotine: EVO
Orka MK4
Rammy mk 3


Achillies, Cacodemon, and Killotine will do well here.

Heat G
360
Bloody Tears 2
Die-Ceratops Re-Invertus
Forcepower 5.0
Forklift 2
Tails

DcRi, will do well. And hopefully Tail =)

Heat H
Dante
FBSDS
Novastorm 2
Obliteration
Wedge Devolution
Wild Thing S4

FBSDS could really rip up the opponents, and Wedge Deco could do a good flip here. Novastorm is another robot with potential in this heat.
