Morning,
Firstly, look through them. A scope can be a very personal thing to the eye.
Once you have looked through them, you will get a feeling - and know what's comfortable.
Myself I have many makes, Optisan, Hawke, MTC, Aztec and now Element - I have to say the Element Helix ( which is not out yet but I have one ) is the best out of all of them. Then Optisan, Then Hawke.
I am making a video on the Helix, for me the glass is clear, the clicks are firm and meaningful and has a zero stop. It works well.
BUT - do look through them, you eye may say no way to the Element and Yes to the Optisan.
