I started out hunting by going after small game with my longbow. I've shot many many squirrels, a good number of grouse,a couple rabbits, a raccoon, and a few smaller birds.
I have tried just about every small game head out there, and have settled on Ace Hex blunts. If I could justify the cost I would be shooting VPA SGT heads though, as they would save me having to glue in an adapter to get my 300gr point. I settled on hex blunts because they don't stick into trees, don't richochet off things like converta blunts or rubber blunts, and they have a sharp enough edge to poke a hole in heavier critters while still beaning small ones quite hard.
Arrow wise I used to shoot a lot more flu flu's but as I have become more accurate over the years I am shooting more regular fletch arrows. I find tree rats tend to dodge flu flu's sometimes on the longer shots. I used to shoot wood exclusively, and made my own shafts. I used oak shafts for hunting mostly, tipped with a 145gr steel blunt.
Right now I have some 2315 gamegetters set up with a 300gr point and 4x3'' shield cuts as cheapo small game arrows for grouse this year. I also have a good number of Easton Bloodline's and a few Easton Aftermaths that I shoot for big game set up with small game heads.
If you are looking to shoot raccoons and the like a zwickey eskimo with an adder behind it has done good things for me. Anything bigger than a rabbit will generally need a broadhead.
As a last note, expect to be suprised at how tough some small game is. Grouse and other birds are pretty delicate, rabbits too but they sometimes run into cover before they expire. Squirrels are as tough as cape buffalo though, I've blasted one with a sharpened field point/adder combo out of a 70# bow and watched it fall from the tree, get up, and run back up the tree until I shot it again, and then still needed to bonk it when it came down! First shot was a chest shot even!
