i am the same as you, a lefty but using right handed guitar. i found it easier to get access to right handed guitars over the years either buying, borrowing... i have been playing right handed but find it hard sometimes pulling off certain techniques. i was tempted a few times to switch one of my guitars to left hand, just to see if i can play better. i hope it works for you, as i find i get frusterated at times with playing guitar and i always wonder if it is because i am naturally left hand but using right handed guitars. thanks to your post i might just try this too. as i have a few guitars and changing one to lefty wouldn't be too big an issue, and i could always switch it back if i do not see any beneficial change.
