i enjoy them -
i enjoy using them over pointing dogs - you generally have a little warning - but i can get the shots off quickly when flushes are the rule
i have a large enough hand to cock both hammers at once on the upland lighter framed gun -i approach the point with the end of my thumb on the front of left hammer spur and covering the right with the base - i can easily bring the gun to cock as i raise it - i open the gun to lower a hammer of any unfired barrel
