You will use the most with your first cut (the F7). I would buy the 1 lb F7 and the C, because you will have to use the C each year when you do a touch up, unless you keep the Bambi indoors. You'll also need S for your final pass, unless you plan to use something like Mother's or something on that order for your final pass. Have fun! I'll be in your footsteps with my Bambi II next spring if I finish the interior, but mine's in really oxodized!
