i don't really enderstand wen you said wobble... i think the real word you need to use is you want a overshoot.
if is that and you really want to stay whit limited key
try whit this options activated

after just take the small handle and modify your curve

for breaking the curve press shift when you take the handle

i hope this is help ,sorry i need time to figure out what you wanted

but if you still have problem you can send me your .max and i will see what i can made (i use max 2009 no sp1)
personally i never use the F-Curve because charter studio don't use-it
Edit: if you check a bit my youtube channel you will see that i know 3d max for animation
