Raul,
I have documented comment from yourself that you have NEVER heard a Glanz, but that you decided not to listen to any of their "G" range because of some prejudice you have about integrated cartridges. Has this position changed recently? If it has I would love to know the persons from whom you bought and to whom you sold it/them - as well as the experience you had and with which Glanz!
The links you reposted are clearly answered and developed on within the course of this thread but that might demand a closer reading. For example, I thought you were aware that I have fully assessed the Astatic/Glanz relationship and can confirm that the performance differences are as marked as the noted construction similarities. All of this is set out in this thread.
Of course, if prejudice is allowed to govern your experience, you can reject anything you like. I would like to think that you would not spread such blind prejudice and ignorance but we are obviously very different people.
As always...
