For next season, my goal is to get as much speed as I can out of my arrows. I want to build my confidence by being able to shoot my block from at least 60 yards away.
Stinkin' thinkin'!
If you base your confidence in your equipment, then you are screwed from the get go. Equipment breaks, wears out or becomes obsolete. So you wind up constantly buying new equipment to get your confidence back or to try and keep up with the times. Of course, the archery industry is based on exactly that principle and the bean counters all hope you are that stupid.
With what you've got, assuming you are already shooting carbon arrows, you aren't going to pick up enough speed to even notice it without a chronograph. There are NO changes you can make to the setup that will give you any practical benefit in speed. And what changes you do make to increase speed will probably cause you to lose some forgiveness and consistency and make your bow more noisy to shoot.
The only way to dramatically increase speed is to buy a bow that shoots dramatically faster than the one you've got. Period.
I'll tell you a little secret about building confidence. The only way to truly build confidence is through practice and experience. Improve your SELF and it won't matter what bow you use or how fast it shoots. Learn how to consistently hit that target at 60 yards with what you've got and you can confidently transfer that skill to ANY other bow.
