Tailwalker, I don't claim to be a centerpin guru, but I do enjoy the challenge of playing a Steelhead without the use of a drag system. It somehow seems to enhance the fight, knowing that it's just you and the fish.
Now when it comes to centerpin rods, it all depends on what you'll be using it for. If you plan on mainly using it on the Vedder/Chilliwack system I would suggest a Shimano convergence I think they cost somewhere around the $99.00 mark. Good rod for the buck, and your not into the rod for buckets of cash. If you plan on using it on the Vedder occasionally and then some smaller streams for steelhead and Coho I would lean toward the Trophy XL and once again they run around the $100.00 range. I use the Trophy XL and love it. The rod has a quick tip, for those casts when you have your back up against the bushes.
Sages are very nice and so is the price, and I'm sure the fish don't care one way or the other about what kind of rod they were caught with. If I can offer my advise, start with one of the above mentioned rods and try it for a season to see if you like this style of casting. One more thing, expect LOTS of winding, but it's worth it. I'm certain that after catching and playing a fish with a Centerpin, you won't go back.
Cheers,
