Bottom walker instead of a spreader?

I posted this over on ifish and I figured I'd run it up the flagpole and see what happened here.
 I tried something different last week because I was out of spreaders.  I tied on a bottom walker that was in my box and danged if it didn't work great. Gear seemed to tangle much less and to come loose from snags much easier. The bottom leg was a bit shorter than 18" to 24" of a dropper, but not that much.

 Other than getting some funny looks on the ramp (which I'm accustomed to anyway), is there any reason why a long legged bottom walker (think extra long legged spreader with the weight on the wire) would be a dumb idea? Can anybody see an obvious flaw and keep me from wasting some perfectly good stainless wire and bead chains?
Thanks!!

If it gets hung up, your bottom walker would probably be a bunch tougher to break off than your mainline.

What I do (and I haven't caught a springer since the Revolutionary War) is rig up a sliding dropper. I use 10# or 15# dropper line so it breaks and all I have to do is tie on a new weight rather than a whole new rig.

p.s. - If you get hung up with 30# mainline (and it's the main that's snagged) what do you do from a kayak? How can you get enough leverage to break that line?

could be an option for a yak specific technique, but the amount of weight often needed to fish your herring correctly during large tide exchanges or river flows would make it somewhat impractical. IMO unless you have a really long leg on the bottom walker you would be fishing your offering to close to the bottom, fish don't look down much. For herring I run a 14-18in dropper, drop it down till I hit bottom then up 2 cranks, puts you about 30-36 inch off the bottom, right above thier noses , and gives your herring room to roll.   Plus the loss of your entire rig when you snag would be a bummer.

Circle around the other side and try alternately pulling and letting it go completely slack from other directions. If that doesn't work I get straight over it and wrap the line around the butt of the rod. That will usually break it.

 Your probaly right about losing the whole rig if the walker gets caught. But the idea of the walker is to use it like a feeler. The tip of the wire touches bottom and will bounce over most things that it touches below the main line. At least thats the idea.
If it hits above the main its probably done though.
