What caliber Encore?
Note that the variable has more parts to break under a heavy recoiler. I even broke a Leupold 2X once on a .30-30. I remember at one point JD would not even consider a variable on his .375...
The Variable is also heavier and bulkier. I have used all 3 Leupys: 2X, 4X and Variable. All are good; all have pros and cons.
Just my 2 cents honed by experience.
