The best way to see how well your bow is tuned is paper tuning
NOT! Just a starting point.
Mechanicals are very good. Remember, the bow you are shooting is a mechanical bow, not a traditional bow. At 70 lbs you have enough KE for mechanicals.
Ahhhh, the easy way out.
I think Rack put it best. They don' t need to aline with the fletch. They must spin true with no wobble at all. Your bow must be well tuned. Even if you choose a mechanical. And finally, YOU MUST PRACTICE WITH THEM!
And also like Rack; Why is this pinned to the top?
