No arguement there. I'm sure guys with your experience can get quite close by just knowing what arrow configuration works with your preferred setup. I'm usually almost exact without much testing, simply because I've done it so many times. However, I often wonder about inexperienced guys. Hopefully they have a talented person at the local bow shop to get them setup properly. My response is for those who don't. I bareshaft because I like getting things exact, even if it's not completely neccessary. As far as the time spent bareshafting, it can be very little if you have some experience at what adjustment needs to be made next. If you don't have that experince, it's even more important that a person does it. I've seen guys stand in front of paper way longer than what it takes me to get the spine spot-on. My point is, if you're not sure what will work, bareshafting is what will tell you exactly what is happening.

I realize that you can have spine off a bit and correct it with movement away from centershot with the rest. I don't like doing this because I think bows that have their rest set to perfect centershot, shoot with more forgiveness when using broadheads. Therefore, if I want to have the arrow aligned on centershot, I can only adjust spine to accomplish the perfect broadhead flight. Bareshafting is the only way I've found to do this well.

I find many beginners and those at an intermediate level of experience, spending a lot of time tuning their bows and almost no time tunig their arrows. It is my firm belief that if they reversed that effort, they'd end up with much better shooting setups for broadhead tipped arrows.
