I think a 9wt. for steelhead is overkill..A 6 or 7 wt. is the better choice..unless you're using it for saltwater or throwing big stuff for LMB or muskies..Using smaller flies, as is the case with steelhead, and using 4 & 5X tippets..the lighter flyline sizes do a nicer job....Just sayin'
While I would normally agree with you on that, the helios2 is a lighter and easier casting rod than my 7wt thomas and thomas. I like being able to lay the lumber to them. Usually in Erie there are so many yahoo's around that I don't enjoy running a fish up and down the stream for 50 yards each way. I also use this rod for lake run browns in NY and Kings, the kings can be 20-40lbs and are like hooking a mac truck. I have a couple 8 wts as well but none as light and easy casting as this helios2
