Whether it be fast cars, fast women or fast bows, speed is nice. You could:
up the poundage
remove a peep sight & or kisser button - go with a No-Peep
go with a lighter arrow
go to a lighter broadhead
plus a few more I' ll think of after I post this.
The problem is, everythings a compromise, lose weight - gain speed but lose momentum. Would you even like a No-Peep? Sometimes it' s not the investment of $, it' s the time that you have to put into it to find out if the change will suit you. If you can, take it slow to take it fast. Too much change at once can affect form & confidence.
