The large mariboo's are incredible musky lures that catch alot of fish and if tied correctly, can also take alot of punishment before needing to be retired. I've been using them for a few years now and have always got at least one rod rigged up with a boo and ready to go at all times.
I always buy mine rather than make them so I can't help you, but musky-man, brick n block & Robin from this board all make excellent musky boo baits and could probably tell you where to purchase the material......perhaps luremaking.com ??
The ones I find best are about the size of a cantalope when dry.
Not sure how familiar you are with these baits, but they are incredibly bouyant so you'll need to experiment abit with the weights to get them to work properly. I've got a couple that are totally weightless, and once they get saturated, they run just under the surface and are excellent baits for bulging over top of the high cabbage, specially with twin blades. I find they work best when run a couple feet above the weed tops or rocks, so, depending on the height of the weeds, it's nice to have a variety of weights. I even clip bell weights onto some to get them down deeper when neccesary.
I've also always found yellow with brass blades to be the best producer but that's just a personal opinion.
I've probably got at least twice as many now since this picture was taken and will be requiring a much large box next season.
Good luck with them and I'd luv to see the photos of your finished project.
