You Might want to learn how to pull a lasher first...read a print ect...Leap froggin' parts of the trade is half the problem with craftsman ship these days . 2/3 of the splicers out there can't bend or handle cable because they never learned how. Climbing , reaching , and handling coax in general takes time to learn it's more than just coring . Not to mention all the different kinds of coax and how to handle them.
P.S. If ya' can only work off a ladder you'll starve !
