I fish with several “high-end” fast rods and, other than breaking off a tip while trying to remove my fly from a tree (my stupidity) I have never broken a rod. I have been FF with many of these rods for a long time. In fact, I still have the original Sage RP (a real broomstick by today’s standards) bought back in the mid 80’s when the Company first began to build fly rods.
Also, the lightness of a rod is an attribute, IMO, but the lightest and most expensive rods are not always the best. Further, for steelhead, a super-fast rod is not the best tool for the job either.
My suggestion is to purchase a decent moderately priced rod that casts well for you. Try a bunch of them before buying one. As you develop as a caster / FF, you will be much better able to evaluate and appreciate what the rod can and can’t do, and choose the perfect rod for the type of fishing you need it for.
