Long focal lenght 2" eyepieces

Hi. I am looking to buy a very good 2" eyepieces for my 9.25 SCT. I want a wide and flat field. I am considering TV Panoptics and TV 55mm plossl and the Tak 50mm LE. I know these are all good eyepieces but I am looking for advice from those of you who have experience with any one of them. I am also wondering about which eyepiece would have the best contrast--do the 50mm eyepieces have less contrast than the 27 or 35mm Panoptics? In general I really like the Tak eyepieces but it is $150 more than TV 55mm, is it justified? I appreciate any advice. Thanks, Gary
