I'm using the SPT 4412LV ($12) in one of my FF-03s, XV-01, FF-01 and LRP S10. All are working great. I used JX before but the SPT just outperformed it in terms of speed, torque, value for the money and looks, I'm also using SPT 5525LV in my MST CFX. While I have Power HD L12HV ($60) in my other FF-03. It's so fast and very responsive.
