Spine target ?

[bccalls2011]

What kind of target do you guys use to spine test a new setup. My old target is to rough to test so I need to find one.
Thanks Matt

If your talking about bareshaft tuning, I like to use a target that won't alter the path of the arrow enough to give me a false reading. I like these type  and keep around for tuning purposes.They seem to work well for me.
