Hi,
if your just wingin' arrows in the back yard, most any point
that fits arrow diameter will be just fine. But ...
if your doing any kind of target that requires a level of accuracy.
my OCD kicks in, an i have to do a better point ... most of my
arrows are Gold Tip. so i do GT points. i also have found some
Victory points that i like. for 3D & spot i like a long tapered
glue in bullet point. both brands also can do screw in fact weights.
if your doin 3D with a buddy or two... GT ez pull will work well. but if
your shooting in a larger group, i like a bullet point. i can dive right in.
with smaller glance out.
to help with arrow removal from 3D target. especially new or cold targets.
i carry a 1" square of ivory soap...
before each shot, rub on about 2" inches of point end.
for my glue in points i like a cool melt. for screw in, you really don't need
an O-ring. just tweak lightly with pliers.
i try to do certain size arrows so i don't need special size components.
that said... i have a micro dia. - a large dia. & what i consider a standard
diameter ( .245/.246) cuz components are easy & cheap to find.
hope you find this helpful ...
just my 2 cents.
