I can't answer for JER or BHD but I really wouldn't fancy doing ABZ or INV in the dash. I'm sure INV has a block time of around 2 hours. I am sure JER & BHD ran with 146's before they were phased out INV certainly was 146 in the BAcon days and ABZ is new to them.
I am sure the 195s were replaced 146 for 195. Guernsey was to get one to replace their 146 but there are issues with the runway down there and there competitor runs with props.
