I have also gone from running an LRP IPC V7.1 with Checkpoint and V2 Motors to a brand new Novak GTB with 6.5 (Sintered)
The change was fantastic for me - i can now practise as much as i want without fear that my motor will die on it's backside towards the end of the day.
I don't know any of the technical info but with the system in and wired up extremely neatly by Trish i am over the moon with it and don't intend on even taking the motor out for a while yet except to clean it!
Will see how it goes this weekend at Lee's but the first time i ran it the motor stayed very cool (could hold with no problem at all) and gave silly amounts of punch and speed all throughout the day on each battery pack.
