I use the Baofeng UV5R which is an earlier model but similar internally.
Yes they do use the Kenwood 2 pin.
I don't use the Bowman. The Z Tactical is a reasonable price and probably best in its price range. However, it does have something of a mixed reputation for reliability and some players have reported having to replace them quite quickly. No personal experience though. Unfortunately, the next models up are professional kit and a very big jump in price and too rich for my blood.
Im not the radio police, but just be aware that although you can legally buy the Baofeng in the UK, you cant use them legally unless you have something like a private business licence. They are too powerful for PMR446 frequencies. I use standard PMR446 radios for skirmishing and use the Baofeng for milsimming where the operators have licence cover.
For example, the Okto Eight Milsim guys who are running the September milsim at the M25 site have a licence that allows players to use up to 5W power on their private frequencies.
