Which fixed eyepiece for my Pentax PF-80ED Scope?

Dear Eagle Optics,
I have a Pentax PF-80ED scope I got from you guys a couple of years ago. I've been using a fixed eyepiece (Pentax XW 14mm), which gets me 36X. I'd like to add a higher-mag eyepiece for a better look at distant little things (peeps will be here soon!), but I'm torn between stopping at 50X (10mm) or going up to 72X (7mm). I'm worried about the brightness and FOV trade-offs, but a fixed eyepiece might make 72X achievable. Thoughts??

Hi Brian, 
Thanks for your inquiry. You are correct about the trade-off in magnification for brightness. I would stick with the 50x--that should satisfy your need for greater magnification, but not tax the performance of your scope with its 80mm objective lens size. Remember, you have a month to try it out with our 30-day Return Policy! 
Sncerely,
Eagle Optics
