Just a guess here.........but it seems like 5shot said he got good flight with Slick Tricks even out of a poorly tuned bow !

Secondly........from what I have learned here.........when group tuning :

You shoot your group at 20 and get it on.......
You shoot your group at 40 and if it's right........you move your rest in small increments left until you get it on........
Then you come back to 20 and shoot/adjust your sight........
Then you go back and shoot your 40 yrd group again....

That's the way I understood it and it works for me.....
Some of my adjustments were very hard because neither my sight or rest is micro-adjustable.........but I pulled them in all the way to 70 yrds by doing the above !!

But...... I by no means...... am a tuning guru !![8D]
