Mewlon 180 EP's

Hello to you all from New Zealand, I have just recently purchased a Mewlon 180 and have been reading with interest the comments in this forum.In one particular thread a suggestion was made to seriously look at the quality of the EP's being used.It seems only fitting to have EP's of a quality to match that of the optics.This is where my knowledge lets me down.Having owned 8 and 10" SCT's and refractors I am left with 16 and 9mm Naglers and a set of Ultima's. I would be greatfull for any advice and perhaps some guidance on possible options.My first impressions of the Mewlon 180 have left me thinking that I will have this one for some time. There really is a difference between average and above average optics. I may not be able to do much about my 49 year old eyes but I still want the best image reaching them. Many thanks, Don.
