There are several good options out there as mentioned in the article.
Most of the bowfishers I know eitherexclusively usethe simplest hand wound spools (cheap but slow),or they have one of everything (like me) so that they can try them out, and have a spare set as backup for a competition or something to loan out when we take out new guys.

Do you have a place near you that has carp, gar, buffalo, or any of the rough fish that may be legal to take with your bow?
