First of all, welcome to the gang!
Don't know about the Weston, but I own an Apple Arrow Saw, and I don't see how you could go wrong with it.
Bitzenbergers are great, but too slow for me. I use a JoJan Multifletcher. I can't tell the difference between how one or the other fletches, so I use the JoJan so I can fletch more arrows at a time.
Feather cut, like most everything in Trad archery, is personal preference. Some guys like one thing, while others want something else. I use 4" parabolic.
I have used many insert glues over the years, including Insert Iron, and am convinced that the Quick Stick hit melt glue from Big Jims Bow Company is the best insert glue made. I use it on HIT inserts, and have never lost an insert in a target, but can easily remove them any time I want!
Hope I his helps you out a bit!
