Since 90% of most fly rod lines are now med. fast, I'll assume your rod is that taper. I'll also assume that the Cortland S/S line in similar to the other 3 companies lines I've used, and it has a short head that transfers into a heavy belly quickly for roll casting purpose. Overlining will not overburden the rod. Short roll casts will be made easier, and handling weight in close. Mending over 20' of line will be made harder, as the tip has to move more weight and resistance. In the end the overlining probably suits your purpose better. I have several 8 wt. lines which I fish on my 7, 8, and 9 wts. They do fine on all of them. Small adjustments in casting make a great deal of difference. As far as turning over weight: some people recommend using a straight leader of 10 pound test, but this will have a hell of a time transferring energy along its length and getting weight flipped. Better to use a tapered leader and step it down to your tippet. Incorporating some small hauls into your cast can make a world of difference. They really can help load the rod. If you're worried about stealth, lengthen the leader- they give you 15' on the SR. Makes a big difference sometimes. There's also lots of techniques for getting down fast without using tons of weight. If you look at discount online fly shops like Sierra Trading Post or Madison River Fishing Co., you can occasionally find these lines at 1/2 price. The sharp rocks and nasty fish of the SR beat the crap out of lines quick. I buy discount or used.
