150x is by far my most used magnification. Very versatile and frames most objects very well. So for me my 17mm Nagler gets used every time the scope gets pulled out. Well worth covering off that area with a nice ocular.
BTW, for you, that's around 7mm - and hey look what just happens to be up for sale in the ep section!
