Fly/bait combo trips can definitely work. I've done more than a few. I do strongly believe that if the goal is less about loading up the boat, and more about the fly fishing aspect, then sticking to flies is more productive for multiple reasons. At least in terms of getting them to eat cast flies specifically.
Braid and fly line tangles don't have to end badly, but that's very angler dependent. The simple reality is that most people don't have the experience dealing with tuna to always know what to do quickly enough for it not to be an issue. I've seen a good six or eight fly lines get cut by braid. It can happen very quickly.
FYI, I didn't mean to give Phil the impression that I was against the idea of fishing a popper. I just have no confidence in the ones I have tied due to their head size causing them not to fish properly, and I have far less confidence in traditional styled poppers unless the fish are showing a very specific behavior. I was trying to explain all that when he asked, but as I mentioned to him, it would take hours to properly explain my thoughts on the subject lol. With the fish being willing, but not easy that day, I did not have confidence in anything tied as a standard popper, and mine are just not right either.
This has been one of the most incredible weeks of albacore fishing I've ever personally seen. Got some weather coming the next day or two, so no doubt we'll have to zero it back in after that's gone, but man has it been good. For reference we put 51 fish in the boat on a single stop today in just over an hour. Just for Evan I got a couple on a flatfall, and then I pulled out the bug rod and stuck one first cast. We finished our morning trying like hell to get my deckhand to catch one on a cast fly, but he wasn't able to seal the deal.
I'm quickly becoming convinced that the manner in which a fly is fished is every bit as important, if not more so than the fly itself a high percentage of the time. I've always heard people talk about fly fishing for Roosters and how the fly needs to track perfectly, swim perfectly, correct pace etc and I'm really becoming a big believer that this is all crucial with albacore as well.
