As you know even the best rifle in the world can be broken while in transit or due to a mishap on the hunt.

I think anyone, most especially someone like you or me that is a quality equipment, tested,proven equipment freek would much rather hunt with his own rifle.
On the trips I have been on, if my only rifle had broken, there was not a spare rifle to be found for me to borrow.

As much as it is convienent to travel with only one rifle to Africa I know I could NEVER do it.

Even the THOUGHT of it scares me.
