As us Loonies know, there is no round that is UTOPIA.
Whats wrong with a 308?
The older I get the more I realize that you can pretty much kill everything with a 308. I've thinned the herd to the 308 Montana, and about 3 dozen flyrods
There is NO FLYROD UTOPIA!!!! But a high end RL Winston 4 piece 5 wt is CLOSE...
