Jeff, first of all, when the ocular is locked, it is far more secure than any non locking ocular I've ever touched.
Another one that's been beat to death. The only oculars you've ever had move while hunting are locked Luppys. Therefore, you recommend in order to avoid this people should only use locked Luppys.
I went into a lengthy explanation not too long ago why your locked luppys can actually be more likely to move under certain conditions. Forgive me if I decline to waste my breath yet again.
I'll simply say, put me in the column of those who have actually used such a thing and never had a problem. But I did have a problem with locked Luppys as you did long ago.
Try a VX-7, E. It has a gold ring! You have to like it! And you might actually learn something....
