Most people who take up micro fishing(since we have no bitterling in the states) will use bait of some sort. Since fishing for true micros would be extremely difficult to do with a fly. You can use what ever you like to use with what ever rod you like. I have been know to use plastic worms and lizards with western fly gear and ice jigs with micro plastic with tenkara. Some people will try and tell you that your wrong for fishing this way or that. Well, I say I live in America and I will fish with what I want, when I want, how I want. I have served this country for 10 years and for some person to tell me I am wrong for expressing my self I will tell them to go take a fly leap. How do they think we got all all the different ways of fishing after all. Some one had to cross the line along the way or we would still be in the ice ages with spears used for fishing. If you want to use bait go ahead.
