My 2 cents worth:

Grudge: AW's Dynamite. reason: a rather back-handed comment I received
FW's: Hornet: did major damage to the robot at the UK champs
HW's: Iron Awe 5 and Ripper: Wrecked our motor with the constant flipping

Side note: Major damage is on our hit list.....

Love to fight: Hortron, The Saint, nice people, and less threatening to fight

Hate to fight: Tiberius, Thor and Terrorhurtz
