holmes hobby cobalt question

[vigilant]

wanna get a cobalt puller in 7t or 10t it will be installed in a disruptor tranny and then to a gcm t case then axial axles. just wondering is the 7t that much faster than the 10t. i want a good amount of wheel speed it will be going in a ttc style truck thats pretty heavy. im pretty much sold on the puller just want to know if a 10t on 3s is that much faster than a 7t on 2s and can they handle water and mud thats it thanks for looking and thanks for the help
