What's the advantage of the double foot

I have built single foot  Micro casting rods, but I didn't have to be persuaded to do it.

The purpose of double foot guides is to withstand expected pressure put on them. In reality most bass rods would work just fine with all single foot guides. I use a DF stripper guide partly for cosmetic reasons. DF guides on the tip are performance killers due to their weight and weight of the extra wraps.

double foot stripper guide in size 5  with micro's out to the tip with a size 4 tip top on ALL my casting rods , including a 9' swimbait rod that is a beast of a rod . double foot guides all the way to the tip ( dobyns swimbait rods ) to me kills a little bit of tip flex , plus as Mike says , makes for a tip heavy rod !

 Swimbait rods in particular or any long rods benifit from single foot guides for the weight savings , i try to save as much as i can , my primary baitcaster is 7'10'' , my swimbait rods are 8'6'' &9' , that's why i use micro guides on everything , including my spinning rod .

What MIke said about withstanding pressure.  That is the reason you don't see many muskie, steelhead, or saltwater rods with single foot guides.  I also like a double foot guide as a stripper guide for the cosmetic value, especially when using tiger or multiple color thread wraps and trim rings.  For longer +7ft. heavy action rods I'll normally go with three double foots from the grip up, but that has more to do with purchasing guides in sets than there being a necessity to do so.

that's my St. Croix 9' big nasty , 1 double foot stripper guide( size 5) , 11 size 4 micro guides , size 4 tip , spiral wrapped .

I usually sugggest using 1 or 2 double foot strippers on a casting rod then getting to the smallest practical single foots (size 05 to 03) as fast as possible.  If double foot runners aren't absolutely necessary, don't use them.  The only freshwater applications that come to mind whre they may be needed are big catfish and musky rods.  I fish singles for  30+ lb wild kings in my neck of the woods.

These will be all large & small mouth bass rods

I've built 2 with single foot guides installed after a double foot stripper guilde.

 

No rhyme or reason for me, just liked the rod that way.
 

Probably go this route

I had my builder build mine with two double foot #6 stripper guides, then he ran single foot foot #5's to the tip per my request.

I use a double foot stripper guide and sometimes a transition guide as well.  Mostly so I can do this.
