The yellow bottle of Sawyers. It is in Walmart I know and several other places. You can also get a permethrin concentrate and mix it with appropriate amount of water. It’s odorless, highly effective, and stays in your clothes up to 6 washes and several weeks. I’ve had great luck with it!
I run a QAD HDX, but I’ve seen guys run a whisker biscuit and trim out the sections that the vanes run through so there’s less resistance, but still arrow containment.
I like to carry mine in hand. Typically won’t have a string/cable cover on it because of possible opportunities while walking in. If I was walking a good ways, I may carry it on a sling more often.
Heard tons of great things about Spitfire Max broad heads so I’ll be using them this year. I used tooth of arrow heads last year and they were very durable!
