i have a legend SL that i bough new in 1998. still a great bow and the only thing i have done is replace the string............ONCE !!!!!as for how they shoot a particular broadhead, i say practice with what you are going to use because they will shoot differnt with defferent broadheads. I shot mechanicla one year and hated them. I use Muzzy 125gr. blades. Super broad head and dead on with my set up. good luck.
