As has been mentioned your form will play a big role in how well things fly. I guess I am lucky as when I started shooting half a dozen years or so back, the folks at the shop I was at, not the workers but target shooters who were in practicing, were remarking how well my form was for someone who had just picked up a bow.
That said I don't consider myself anything much more than average. I don't shoot groups much though I find it gets very expensive. I have set up my own bows almost since the beginning. It isn't hard just a bit time consuming. There are a couple of links below that will help you out greatly in dialing in your bow, but again, YOU are the determining factor. If your form is up to snuff, and your shooting up to 50 - 75 shots per session with out getting tired, you can get through the paper and walk back tuning pretty quick and easy. Lots of folks will go with one or the other, I went with both. I figured if I was spending the time to screw with it at all I might as well give it all a try. Good, bad, or otherwise, I usually hit what I am aiming at out to 40yds.
Anywho, here are a couple of links,
This one is about the best as it goes through plenty of the basics and will get you into small groups with straight flying arrows, I suggest you save it to your PC as the links for it come and go.
Easton Tuning Guide
For straight up paper tuning this is about as basic as it gets,
Also you might simply do a search on "Tuning a Bow". It will bring up plenty of info. Browse through what comes up and you will start to see pieces pop out repeatedly, Those pieces usually work over the broad spectrum. Another thing is don't just rush into this and think "hey I'm gonna do this when I get home from work". Take a full day or two, to work through it a little at a time and you will be MUCH better off. This keeps you on track with dialing things in right, and you don't get tired from shooting which will induce other issues while your trying to adjust things.
As for true flying broadheads, I have used half a dozen or more and find that once the bow is right, the arrows are right, the flight will be right. I use heavy spined arrows in all my bows, I shoot 340's at 29" so I know that even if I back the pounds down to 62 or crank them up to 70, I might be a bit over on one but still within spec on the other. Speed doesn't help one bit if you can't hit what your aiming at. I can easily hit 265fps or better, with each of my 3 bows shooting 430 and up grained arrows.
I guess what I am getting at is way too many folks get caught up in trying to get 300+fps using light arrows. This is all well and good if you have the proper one to do so, if not your inducing issues into each shot and will never be able to tune things in right at varied distances. You might get it great at 20 but at 30 things are going to be whacked. Dial it in at 30 and find that 20 is whacked. You end up chasing your tail.
As for a brand and type of head I would recommend, well after using the half dozen or so different ones mentioned above, I have settled on the Slick Trick- Razor Trick. To date I have not pulled but two out of several dozen that when screwed into an arrow were not true. I contacted ST and was sent a new pack.
When I set up, I number my arrows, and my BH's, then I shoot them all until I find which ones shoot the best. I have more issues with arrows than the head. Once I find the best I set them up as a matched set, head to arrow. After that, I have no issues simply screwing a field tip in for practicing, and then swapping over to the Razor Trick to go hunt. Even with simply pulling the new heads out of the package and screwing them in, I have no issues heading straight to the woods as I have shot enough of them to know that within 20-30 yards they will hit usually better than I can hold.
One last tip I can give you is to aim small, hit small. Use targets that are just big enough you can focus on them at what ever range your shooting. I use orange foam ear plugs and find out to 40yds they have improved my accuracy twofold. If you look at the Archery folder at the link under my sig, you will see what I am talking about. The first pictures there are at 20yds and from a week after picking up a new bow. There are others posted in Shooting Groups, also after picking up a new to me Drenalin, which are out to 40yds, and a couple that I have shot both right and left handed as well with my Tomkat. You will see how well the ear plugs show up and how well they can be dialed in on, and also why I don't like shooting groups.
Good luck and hope this helps.
