As a relatively new person shooting HFT, I concur with Chris's observations. I haven't a great deal of experience unlike most of the shooters. However I have tried(bought)numerous scopes new and second hand. There again I have done the same with rifles, searching for that perfect setup.
My downfall was not giving time to see if the setups/combination would work for me.
Reading and more importantly listening to sage advice,I have made the decision to concentrate on one setup for the next year. Adjustments and tweaks along the way will be part of my learning.
On a final point, I do feel more settled and confident that this is the way forward for me
