It's probably best to have all the accessories you intend to use on the bow, just like with all other tuning procedures. But really, what I am interested in is how the power of the limbs are balanced around my grip. Counter balances and stabilizers might interfere with the bow's reaction, make them less noticeable. I do it without additional weights first to get the most reaction I can. THEN I add all my stuff and double check with it on there.

I've noticed that a lot of times the extra weights and heavy stabilizers are simply countering the effect of unbalanced limbs. Equalizing the power of thethe limbsmight allow you to dump a lot of that excess weight. Depending on the bow and your shooting style, it can make a huge difference in how a bow feels and handles.
