I'm not totally convinced that higher FOC works that well with aluminum and wood.I just use a 125 or 145,150 gr.point on most of them and don't worry about FOC,it's usally around 10-12%.With wood I always liked tapered arrows,which will give you alittle higher FOC,but nothing like carbons.There are so many more spines available in wood or aluminum.Higher FOC with carbons works very well because they recover quicker.And that usally is what is needed to tune them,because they don't come in as many different spines as wood or aluminum.JMO
