A litte blown away, eh?
Some good suggestions here. I have the 16mm ES 68° and while it's indeed a great EP, its eye relief will probably not meet your requirements. Same for a 19mm Panoptic. The TMBs & their clones are really good also but don't come longer than 9mm. Anything that does is not based on the original TMB design.
Consider a 17.3mm Delos or 17mm T4 Nagler
second hand. Probably the best value for what you are looking for. I've bought a few used EPs (including here on IIS classifieds), and they had all been well looked-after. Failing that, 17mm Vixen LVW.
