I remember your post on that group, welcome.
I am afraid I am not the best on this thread to advise on OH, its a discipline I gave up a few years ago. I have lost some dexterity in my left hand with age which I can hide in 2 handed solving but it is obvious when you see me solve a megaminx as all my U and U' are with my right hand on that puzzle.
I solve(ed) OH with the left hand though I am right handed for the same reason as most. Right handed 2 handed algorithms suit left handed one handed. The reason being is a lot of 2H algs are R and U heavy and in the left hand R and U are easy, U with index and R with pinky.
I would concentrate on finding sites that specialise in OH algs now rather than learn 2H awkward algs and then have to relearn later.
Here is Antoine Cantin's site, he is one of the best OH in the world:-

You may ask why I have linked a LH OH site but these are very optimised algs and if you pick a mirror case and L/R mirror the alg it may prove useful. e.g. Ja for LH is Jb for RH with teh alg mirrored R to L, so R U R' U' becomes L' U' L U.
Hope that is of some use and again, welcome to the old mans mad house
