Certainly I could point out that "the review from the other website" that first started this whole Pixy craze was done as a bass reel in its stock form.
But more importantly, I own a couple of Pixy reels myself (both LH '04 Yellow models), so this is more than just theory or conjecture on my part. These reels been used only for finesse techniques for bass and walleye on light line, and they haven't given me any reliability or performance issues when used for these purposes. Maybe you're using them beyond their original intended purpose?
For trout, the drag would need to be smoother that what the stock Pixy offers -- but that's what the Presso was for. For the record, I did upgrade the drag on my reels -- but this was more for smoothness than to up the overall power. After all, I'm using it with nothing more than 6lb line (or 10lb braid with a max 6lb leader).
I don't have any experience with the Steez reels, so I can't speak to whether or not they're any good as a bass reel. I do find it a little surprising that a flagship reel would be unsuitable -- if that's the case, I'm surprised that Daiwa is so revered among the tackle enthusiasts.
I guess I should be glad that the rest of my stable consists of entirely of round Shimano DC reels (although I do have a T3 on the way). Don't you love the irony?
