Noodle Rod Sizes

I'm trying to find out if there is a rule of thumb as to the length of noodle rod one should use. I have seen them from 10-13'. The 13 foot they said was a float rod but would it be good in the mouth of the tribs in Lake Erie. Does the line weight play a part to the length, ect. 

I used to use a noodle rod but I gave it to a friend..i would suggest a 10 foot ugly stick fly rod..

I have a 2 piece 11 1/2 foot Lamiglas and hate it.
The rod is too long to fit in the trunk or tool box.
The extra length seems to get hung up in the trees where I don't have that problem with my 9 or 9 1/2 foot poles.
I just seem to loose track of where the tip is behind me when casting.

A 9-10 foot rod made for 4-8 or 4-10 pound line is probably what you want.
Look at the lure weight also.
A rod made to throw 1/2oz poppers will seem like a telephone pole if used to throw a 1/16oz minifoo.

I have a noodle rod made for 2-6 lb line but have never used it-don't want to play a fish that long and never use 2lb line.

Some of my noodle rods were quite expensive but I actually find the outdoor store brands to be just as good.

Absolutely love this rod in 9'

Generally use 6# mono, but if conditions are on the low, clear side, I'll switch to 4#

Have fished with 10'6" rods and really prefer the 9'.

There is no hard, fast rule on what size noodles that people use.  As discussed above the variety of people you see in Erie using different length rods is endless.  Generally speaking, when you are fishing in Pennsylvania you do not need overkill in your noodle length.  If you were to take an average of rod length from different anglers my guestimation would be 9'.  Since the streams that you are fishing are usually not too large, that seems like a fine choice for me, and personally that is what I use as well on the rare occasion I spin for steelhead. 
 
But, you did mention fishing the creek mouths...and float rods
 
Float rods are generally tailored for use with a centrepin reel, an excellent tool in the right conditions, but might not be the right choice for a spin reel.  If you plan on fishing the creek mouths, (im assuming with a spoon or flatfish)  then you might want a little longer rod with a more moderate action to compensate for the weight of the lure and the long casts you will be making.  Iv'e seen many a cleo get hurled into the lake making a long, 2 handed cast with a whippy rod. 
 
Also, consider the style of handle.  A west coast handle has a longer foregrip and a shorter butt, while a traditional handle is just the opposite.  The west coaster is good for doing the drifting type of fishing, where the traditional would be better for casting.
 
Hope this opened up some options for ya.

Doesnt it fit in the reel seat?

I used a 9.5 ft. ml bass pro float and fly rod this year.  Caught some steel on it worked fine.  I Cooked the shimano reel i had it on a big un' over vets. day.   I replaced it with a penn sargus.  I 've used longer rods for salmon and browns on the niagara ( shimano convergence 12.5 ft. it casts like a wip)
If u want to cast a spoon to canada or hold 40ft of line of the water to float its great. but its a situational advantage or sometimes disadvantage.  I like to get a happy medium between long and just right and to me thats a 9 to 10 ft stick.
 

The reel is a tank, Ilove it! I got the sg3000 Its heavy, in a good way.  I dont like grafite reels especially on hard fighting fish. The frames always started torquing. Not the sargus.  It is all metal,  and i heard of guys using it in salt. The only draw back no spare spool.  Its a good purchase!

ive got a 11 6" rod and a 10 ft i find my self useing the 11 more but ill also trool the rivers and use it as a out rigger rod and 8lb fireline dia is around 2 lb heavy and the steel head are not spooked by it

I got a 10' cortland from poor richards last year...Love it....Has a lifetime warranty to...Doesn't matter if you break it fighting a fish or you run it over with you truck...They will replace it free of cost...I also use 4lb Pline on mine...I have always had better luck with the bigger leary steelies running thinner line...I know some people that even run 2lb on noodles...My freind also has a fish eagle II rod that I use...Nice, but overpriced in my opinion....
