Shot some solid aluminum arrows, many years ago, but they bent way too easily. The latest versions that were out a few years ago were 2040's and they were very stiff, never measured them, but they shot pretty well out of heavier bows, but still would bend. We have a laminated aluminum/fiberglass shaft in our Predator arrow, but it would be too stiff for most bows unless you shoot 65# or more and they are about 400grs heavier then a fiberglass arrow. They work great in our Gator Getter setups and for heavy bows and deep water fish.
Some new carbon arrow varieties are coming out on the market but most of them are stiffer then standard fiberglass arrows and usually do not work well on normal weight recurves, most of them are setup to shoot off compounds and they do pretty well. But as far as making a specific shaft in varying spines for different bows, there is just not enough market to substantiate the cost of production, packaging and marketing to facilitate that. We are the largest supplier of bowfishing equipment to dealers and dist in the country and still the numbers on bowfishing arrows we sell is not a drop in the bucket compared to hunting shaft sales. There is a tremendous cost in producing a new product and the sales have to substantiate that effort.
For example, the brass inserts, took me awhile to convince everyone on the value of offering those inserts, but fortunately they did take off and have done well for us, but definitely not a big money maker by any means, but it had another value as offering more people a better method of using our broadhead on their arrows, so that contributed to the value of the item. If bowfishing continues to grow and the demand becomes substantial enough, then new products and specific products can be warranted. Thanks, Mark
