I have been bare shafting and to get my arrows to fly right with 150 grain tips, the arrow is 31 inches. Seems to stick out a lot at full draw. I know I could add more weight up front, or go with weaker shafts. But I was curios on how long is too long?

I always shot what bare shafted personaly didn't care what the length was. Not an issue now after Rods class have a 31.5" draw. Need to get spine closer not much to trim off full length shaft.

Primitive societies shoot 6 foot arrows.  For me that would be to long.  4 or 5 inches sticking out front is no big deal.

3 inches from the point of contact on the bow to the cut on the shaft is about optimum from my experience.

Long arrows are ok, I like longer ones to get the weight I want...

What ever it takes to hit where you are looking at! Just my $.02.

Are you talking about carbon arrows? With carbon arrows I let my bare shaft tuning determine their final length.The length doesn't bother me if my tuning is where I like.I bought some used carbon that were cut 1" past my draw length and they were showing stiff.So I added more weight up front and they were showing even stiffer.On my longbow cut off center they were bouncing off the riser instead of flexing around it.They would not tune no matter how much weight I added.So now I start full length with the weight upfront and trim and tune from there.With a longbow cut off center I like a longer arrow if I'm shooting carbon arrows.

Yes they are carbon CX maxis. I did some more tuning and it looks like I will be shooting 32 inch arrows from tip to tip.They shoot as good bare shaft as the do with feathers.

The deer won't care if you have alot of arrow sticking out.

If you use point of aim for your shooting, it could help to have different length arrows, kinda like golf clubs.   "These here are ten yard arra's,  these be 20 yard arra's . . . "

I leave my arrows as long as I can - for some reason, it's easier for me to aim that way.

I only worry if the arrows are getting too short-broadhead slicing finger-never worry about them being too long.

My draw is 30" and my aluminum arrows are cut 32". This leaves about 1.5" from the back the sharp broadhead to the knuckles on my left hand when I'm gripping the bow. I've never sliced a knuckle doing it this way.

If they're poking into the deer before you loose the arrow, I'd say they're a tad too long.
