Haven 't been doing it as long as Ronnie, but a good couple of decades and a little more is what I 've got ( Ronnie is older than me ya know , he was ketchin them big momma basses when I was in diapers ), besides, back then during the age of the dinosaurs when we had to dodge velociratpors in order to get to the lake and catch some armored feesh baitcasters were only manufactured in RH versions and you could choose between RH and RH.
Besides that, if you do so, not palming the rod and reel and maintain the handle in your hand just like Ronnie mentioned, then you will have absolutely no control of the rod rotation while under pressure. So wether you like it or not you still gotta move the hand forward after the cast to palm the rod and reel, for us old farts that had to learn to shift hands cuz we had no LH BCS back then it takes us the same ammount of time to shift hands that it takes you to move forward the hand to palm rod and reel.
I agree completely on Roger 's opinion
Right on !, this is like learning shift gears on a manual transmission vehicle, once you have developed the coordination which is only achieved by practice there 's no difference between either, as a matter of fact, it becomes automatic and you aren 't even aware you are switching hands.
