I've followed Al in a canoe enough to know that he practices what he preaches. The number of casts, and accuracy of casts in a day is greatly increased with a baitcaster. I agree that if I were a beginner starting out again today and were right handed, I would learn on a left handed baitcasting reel. Why waste the motion of switching hands for the rest of your life? Efficiency catches more fish at the end of the day. The best is if you learned to cast with both hands like a switch hitter in baseball, so you could work both sides of the river equally.
Funny, I'm used to a right handed baitcasting reel but when I use a spinning rod, the reel handle is more comfortable on the left side.
