Spend the money and buy the bitzenburger right off.
Then you have to decide whether you want a right or left helical or just a straight with offset.
I offset my helicals as much as they will go and I use......................
left helical. Does it make a difference some say it does some say it doesnt, I just think it is personal preference and I dont like to do what a majority of people are doing in their set-ups
You can either use feathers, vanes (4" or 2") I would personally recommend you to blazers if you already havent tried them. Very durable.
Alot of people use Goat Tuff, I had sticking issues and switched to Pine Ridge Fletching glue and had no problem.
You will also need denatured alcohol for cleaning the shafts especially the inside after you cut them to your length for better insert adhesion
Cutting arrows, my buddy bought a Cabelas arrow saw and works awesome.
When cutting arrows make sure you are cutting them to long for a weak spine or to short for a overly stiff spine, remember a little stiff is better then a little weak
For example, I have a 29.5" draw and shoot 28" arrows, Im about a inch or so past my rest.
Good luck and it is a lot of fun.
If you have a buddy close to you it is a lot cheaper, I bought the clamps and he bought the saw and we borrow each others stuff all the time.
