Mine are pretty old.  "Featherlite" is what they were going by way back when.  I had to replace a some a couple years back and, yes, I noticed they are being called "flutter" spoons nowadays.  You can get them in  4 or 6 inches, silver or bronze, hammered or polished finishes, or even silver on one side & bronze on the other.  They weigh next-to-nothing and pack very efficiently (ie. I can store six or seven in a compartment that generally holds but 1 lure).

I've caught all the Big Four on these spoons.  I may occasionally put on a two oz clip-on but seldom more.  They really don't need to be trolled any deeper than 25-30 feet, even when LT are quite deep.  I've had big trout come up from 60-80 feet to hit them in 20-25 feet of water... the "flash" is that good (particularly silver on a sunny day).  Mostly I use them on lake trout when my Options # 1,2, & 3 fail to produce.  They seem to work really well when you know the lakers are hitting on Ciscoes.  I've also had big deep-water pike come up for them but then again what won't big pike hit? (Option #1 on big pike = old, rusty Schlitz can pierced by mega-hook; use 6oz sinker to counter-balance air bubbles in can).

Basically, I like them because they pack easy & are a good 2nd option, multi-species lure.
