I've never been able to afford a Leupold, apart from one which I had a few years ago, it was a front focus jobbie with a PR conversion to 18x-40x, and it shifted with temperature unacceptably in my opinion. Now I have the opportunity to go for a new 35x Competition series or a second hand Mark IV with PR conversion to 32x. Similar money. Having never handled either, could a member with knowledge and experience of both give me some pointers, please, as to the differences and the pros and cons. It's for FT and would be going on an early EV2.
