think the original 190 might now be 190cl (classic), one pod i spotted as 190 (no letters after) was legs only, other designations might be for different centre colums and colours. The difference between models is quiet small, but I would probably buy one with a B desigation as black allwasy better for wildlife, or think they do a green one as well.
