Straightarrow or anyone, I actually am not familiar with the brass inserts, what weights do they come in where do you get them, are they like the steel inserts, what is the angle size?
First, Gold Tips are made by Gold Tip. The brass weights attach to the inside end of the insert. They are threaded as well as that end of the insert. Any Gold Tip dealer should have them.
Well, by all indications the 5575 will be too weak. The perfect arrow would be a 3555 with about 200 grains in the front either in weights or points. I think the 5575 will fly stiff for you. I don't think you will be able to add enough weight to make them spine out at that low of poundage.
I think he meant they would be too stiff. I think he's wrong. You can add all kinds of weight up front if you want to. Broadheads are available up to 220 grains and even higher. You can get insert adapters (attach between the insert and the broadhead). You can add a couple hundred grains in brass weights internally. You can definitely weaken them enough to use. The question is, do you want to. By the time you buy the new broadheads and/or weights, you may not save much money. Though in my opinion the extreme FOC you'd obtain would be great for hunting.
