The Cat will be faster and easier to drive because it's belt drive.
The Serpent S-600 is probably not pokey either, with it's futuristic
appearence etc... Both look like great cars.
I'll be racing against a Cat SX and Serpent in the near future.
There's a guy down my street that is a sponsored driver for mugen seiki
he plans on getting one of these, but I guarentee you it will be Cat SX.
Because he ran Shumacher ball-cups on his 501x when he had it, so he
could ditch the stock servo saver. Which it worked out for him.
I could see him driving a Cat SX in the near future this year.
Wesinator might keep the pred, or sell it to get a Serpent S-600.
So reguardless I'll be racing my 501x "WCE", and B44 against these. I cannot wait!
