Fly line help

Picking up a TFO 11' 7-weight switch rod.  Looking for suggestions on line for it.  Was told that a regular steelhead line would work, but would like some kind of feedback from anybody who has one or has used one.  I have a line I will use for normal overhand distance casting but would like something for the spey cast direction, just for the times when there is no backcasting room.  Thanks in advance!

Normal line will not be the best for this rod...


Where and how do you plan to use this rod?
type of casting?
type of flies?
type of fish?

I am getting this rod mainly for fishing lakes. Flies will be 3-5" both weighted and unweighted.   I have a bad shoulder and like the idea of not having to double haul with the single handed rod in order to get long distance.  I casted one the other day and it was no effort to put a LONG line out.  I know the line that will go on it will be more than fine when it comes to two handed overhead distance casts but not sure if it will do the job for spey style casts. 

Now that I know what that you are not going to just use this as an indicator set up I will help alittle more. You can not beat a compact skagit line for sunken anchor spey casts. Pretty easy to pick up and very fun to launch. Another line you may want to look into is RIO's outbound. From my understanding this line performs well single handed and 2 handed. I have never used it but I have heard good things.
 
The most important thing is to find the grain window of your rod and match a line to it. Call TFO and talk with sombody there about this, and I dont mean the broad answering the phone. Ask for a tech. They should be of most help. I would guess the grain window of your rod is around 350-475. Remember to allow some grains for a tip of t 11 or t 14 or whatever you are going to use to get down. Once TFO gives you some choices look into Red Shed Fly Shop. Sorry I am to lazy to give you the link, if you want to find it you will do the work. Poppy has many different spey lines that he will send out to you to try. You just have to pay shipping and return them. Try it before you buy it type thing. That way you dont have to spend a ton of money on lines that will not work for you or just simply dont like. Hope this helps and enjoy.

Are you going to be looking into sinktips?
if so...like swinger said... look at the compact skagits
 
there are also switch specific lines...
 
the guys at TFO are super helpfull... so is speypages
do some research and think about what kind of casts you want to work on the stillwater
 
but remember the 3-3.5 ratio
in general... you head and tip sould be 3 to 3.5 times the length of your rod

everything that anyone tells you is their opinion...
 
try it out... get the feel
find what works... fix what doesn't
