I have built a couple rods, one of which was a fly rod. It used an uplocking reel seat, just because that's what came with the kit. It seems that most rods these days are uplocking, as well. Can anybody tell me what makes one better than the other, if anything? Is the balance affected that much? Is it just personal choice? I'd like the folks here to give me their ideas and opinions, as most of you likely have much greater experience than I do. Thanks.
