Ifrit's whooptey big flu-flu feathers would help counterbalance the lack of weight forward.
A weighted point on the arrow literally drags the arrow behind it toward the target. If you put the weight at the nock end, the back would want to pass the front end, causing the arrow to do highly erratic things. So a neutral balanced arrow like he is proposing would be somewhere in between, the fletching having the final say in what happens. If the shafts are light enough spine, they should fly just fine, but most production shafts are spined to accept a 125 grains of weight forward.
