I had 8 X 56 Swaro Harbitch or however you spell it
Now I use 2.5 -15 X 56
Fixed+ Light weight, best light gathering, no faffing or accidentaly leaving it on full power when you have a 20m shot in the woods and the big one.... Cost
Fixed - 6 X often too powerfull in woods. 6X not powerfull enough to boost confidance for long ranger shooting. Even zeroing at 100m is MUCH easier with a 15mag scope
Variable + 2.5 for woods 15 for long range works fantasticly well, Zeroing made easy with higher power scope, confidance for long range shots
Variable - Heavy, Faf inducing and can induce errors of too much and not enough magnification (but you soon learn to check it) Light gathering will never be as good as a fixed but who cares its plenty good enough, COST
Having had both I feel the 2.5 15is I use for stalking and the 6-24 I use for fox are the better choice
I did get a swaro Z6i 5-30 but it was a bit too heavy / powerful for what I needed. The Bushnell I now use in 6 X 24 is much lighter and easier to live with
I also have a Vortex Viper HS LR 4-18 which for the money puts my Z6is to shame on how expensive they are.
