1) A step too far for me. Unnecessary and just another thing to fail and add expense that's not needed.
2) I see the suggestion that drags aren't very good quite frequently. It usually comes from people that think that old Mitchell reels are fantastic!
3) Again, too much. I don't want to be buying a new reel when my alarm goes belly up or vice versa.
I'm quite happy with the way modern reels are heading. Lighter and more hard wearing materials continue to be developed but I don't feel the need for drastic improvements. I just hope that they don't get more fragile in the pursuit of weight reduction.
I'd like to see the back of pathetic little bits of plastic as line clips. That's about it other than the wide, long shallow spools I mentioned earlier.
