What accomodations can Be Made With arrows When changing poundage due to Injury? I don't Want to start cutting them down. Is there a good strategy here?

Unfortunately injuries are commonplace in the sport of archery. Such events usually mean a drop in poundage whilst we get ourselves back on track. Arrows normally have a correct operational range of just 5 lbs. A significant change will usually mean that correctly spined and tuned arrows will now start to shoot too stiff. Cutting an arrow down will actually stiffen it even further. The arrow really needs to shoot weaker due to the lower power levels. Without adding power or length it's very difficult to weaken a static spine deflection. That said there are a few things that we can do to weaken the dynamic spine.

Dynamic spine is how much the arrow bends whilst it is in flight under kinetic load. The biggest change will be had by changing the point weight for one that's much heavier. This makes the front decelerate much quicker. The back of the arrows tries to catch it up and causes the arrow to bend more in flight. The static spine remains unaffected.

A change of nock can also add at least a fraction of length to an arrow. Not all nocks are created equal, brands and models differ in length. For example changing from an Easton pin nock to a Beiter will add at least one eighth of an inch due to the nock groove being in a different position.

Another very small change could be a change of vane. A shorter and lower profile vane will reduce rear end drag which will effect a small change in dynamic spine. If bow tuning and the dynamic spine adjustments don't give you what you need, you'll need to consider a new set of arrows.

My advice would be to find a set of suitable, good quality used arrows. Chances are that you'll find what you need at a bargain price. This option makes sound financial sense as these arrows are only to get you by. When the recovery period is over you should be able to sell them on for more or less the price paid.
