Before buying any arrows for this bow, he needs to have the bow put on a scale and have it drawn to 33".
If the bow is "really" around 40# at his 33" draw length, you might want to throw into the mix a full length 2215. It's considerably lighter in weight at 10.7 GPI (grains per inch) than a 2117 which weighs 12.0 GPI (grains per inch). The 2215 would have a big advantage, trajectory wise, at 20 yards over a 2117.
Besides point weight, he'll have to play around with brace height no matter which of the two arrows he chooses.
As for a 34" arrow, I don't think he'll be able to find this length in the appropriate spine for an aluminum arrow. The low poundage and his long 33" draw length is working against him.
