I have only tried this on a couple of bows; but have been able to get the bare arrow shaft to travel straight, and hit the target in the same spot as the fletched shaft out to 30 yards -with the Easton Axis arrows. Like you hardly needed fletching, except for broadheads.

I played around with some 4000 series Blackhawk Vapors awhile back and, although they shot well with fletching, always showed a stiff spine reaction with the bare shaft. In this instance, the nock was about online with the point of aim and the point was off to the left about 4" at 20 yards. And at 61 lbs. and with a 28" arrow, I very well may have been a little stiff. I have heard these 4000 Vapors are a little stiffer than an Easton 400 - plus the I cut the Easton's an inch longer.

In fact, I arrived at the 29" length on the Easton 400 shaft by starting out shooting a full length shaft - and cutting an inch at a time off until the bare shaft shot with the fletched shaft. The Vapors were already cut to 28", so no opportunity for this type of tuning.
