Capacitor

Hi all,
i'm just started planning to build a coil, did get 20kg of .71mm enamel
wire from salvage yard,
enough for plenty coils!
right nowww they have a box full of  5uf 8kvdc cappacitors at $A65 each,

they look good too, made in ireland.
Only I suspect the capitance is too high!,  sure series connect them,
but there $A65 ea,

do any of you have an idea of what the highest capicitance you should
use for a
tesla coil?
i've been seeing various info on the web, and typically is 0.2uF

thanks for any help
