Downshifting

[wmtee]

At a couple of the tracks I have done DE's there were long straights that produces good speed(110/115) and then into a sharp corner. I am in 4th at the end of the straight and have been shifting into 3rd but I think I need 2nd. I tried to downshift from 4th to 2nd, but it didn 't seem to work. What is the solution to this? My heel/toe technique is not very good, this is what I will be concentrating on for the next few DE's, but what I need to know is do I go from 4th to 3rd, and then to 2nd or is there a way to go from 4th to 2nd. I am just losing too much trying to come out of the corner in 3rd. Bill
