How much speed do you have?

well, i can make another update to my speed, if i plan my build right, i can max Strafe, Rain, MB, Puppet, and have have 10 points into thrust and 1 into inferno. At that point, ill have 20 points left, and i have hawk at 20. So, I can max hawk, and have another 10 points left, would it be better for me to max thrust, or to get 21 inferno.
