These "Q70" EPs are the worst mismatch for use in Newtonians. I looked into these and showed the worst astigmatism I've seen in my fast Newt's - starting from 25% out from the centre of the FOV. The Q70 range is the same EP as that mentioned by Sky, just rebadged.
The GSO SuperView range leaves these for dead if you are after a modestly priced super wide EPs. The Superviews are cheaper too.
These Q70's are better suited to very slow SCTs & Maks.
There is nothing wrong in going BIG with the exit pupil. Sure, not all the possible light can enter your pupil, but it's not like you see jack. I use a 34mm Meade SWA in my f/4.5 & f/4 Newts for extra kick in the TFOV (I limit my AFOV to 70*), and it is still good using it from my home in Sydney.
I even have a 65mm plossl. I can only use it in my fast Newt's from a dark site, but it is a gorgeous EP, showing no aberrations at all as these all lie outside the critical optical point of the lens arrangement due to the barrel limited AFOV of 40*. Though small, it is comfortable to view with.
All long focal length EPs will start to show an increasingly bright back ground, particularly from urban skies - it is not limited to large exit pupils. What an over large exit pupil will do is effectively stop down the aperture of your scope (the bright background is a given from urban areas). It's not like you see nothing in a smaller aperture, is it?
A 40mm EP will still be very, very useful with a fast scope, and the sky glow won't be too much to render it useless (a 50mm will from the big smoke). Over large exit pupils is unnessarily over rated as a detriment. If you know what it does, and work with it, EPs that give these are still very useful.
There is one thing that will help you see more from urban skies too - use a smaller aperture. The smaller aperture will proportionately give less sky glow, allowing for better contrast. I saw this with comet Lemmon, where it was much easier to see its tail in an 80mm f/5 refractor than an 8" f/4 reflector.
