Cattails sinkers... should i or shouldn't I ??

[fish raptor]

I am getting things ready to pour some sinkers and was wondering if I should consider adding these Cattails into the mix.

I purchased a few but have yet to use them. I believe they are meant for a very slow troll or drift to keep you from loosing the rig cause your sinker getting stuck. I would guess they would not be used for a faster type trolling situation ?

Has anyone used these or are they more of a gimmick ?
If you have did you have any success ?

if I do add these then I will have to purchase some SS wire and possibly one of the haywire twist tools, their are quite a few out there.
I know you can do by hand but tool is cheap and probably easier on the fingies. I mic'd up the thickness of the wire used in the few Cattails I purchased and would just emulate the thickness and lengths.

.051 x 10" long for the 2 & 3oz
.062 x 12" long for the 6 & 8oz

Never purchased any wire before, any good spots I should look at ?
Do I buy a spool are loose pcs ?

thanks
