I have the utmost respect for shooters of every discipline Rob, and have a very clear picture of what it takes be a winner in that effort.
Especially a consistant year in year out winner. I also know that the best, don't always end up winners, but the winners always are.

Those of us that prepare for this, don't lug benches to remote areas. They've already been stashed there for years in most cases.
As with many things, proper preparation is important, and can in some cases cause losers to be winners.
