Bob, I'm sensing people here just don't have experience with this particular combination and sense a nervousness or hesitancy around your order (weather that be accurate or not, it does appear to be evident). So, they are actually trying to be helpful in the one way left that they can be, by attempting to reduce your nervousness until they arrive and you can hear them for yourselves. At this point, discussion would hopefully reconvene and it would actually be you giving us the value of your new experience.
In general, I find the veterans here to be very forthcoming with opinions when they have them and do a good job to try and remove as much subjectivity as possible by backing it up with fact or stating that they are indeed subjective opinions.
If further subjective opinions are strictly what you are looking for, here are a few Google found for me. opinions 1 Opinions 2 Opinions 3 Opinions 4
Most seem positive but are not the subjective comparison with an M80 you are looking for.
