The past few trips out, I've landed some pretty decent size bass on Betts poppers. Not the larger ones but the smaller ones. I like to use them because If I bass isn't going to hit the fly, I expect a bluegill to slam it. A bass bug doesn't have to be large or a deer hair bug. I'm only saying that because I'm a gear minimalist and like to take all I need in one small fly box. Sure, it helps to stir up the water with a deer hair diver or something large that causes chugs and bubbles. But at the same time, it sucks to lose a deer hair fly that you tied up yourself or a $5 bass bug. You can buy Betts poppers by the package at the store and online for cheaper than a bass bug. So, it doesn't bother me as much to lose a cheap fly. After all, don't bass like cover and nasty places to live and hide?? Plus, some of the places I get into don't leave much room and I break flies on the back cast or up in a tree.
To those beginning to fly fish, you don't have to spend big bucks to enjoy the sport. I don't like to spend much on the hobby myself. And as many flies as I lose, I try to tie my own or buy them cheap. Plus, when shopping, Betts are easier to find than other flies - you don't always have to hit the fly shop for them and not every metro area hase a fly shop.
Betts are small and light enough that you can cast them with a regular fishing pole and casting bubble. This helps if you are in a real tight place to cast or are using terminal tackle such as rooster tails or plastics. It doesn't just have to be Betts that I am saying you can use but also could be Mepps or other small popping bugs.
