Go with both and if you are not too dishearted,try Mysore again too
I know i will...
I think that once you have Mysore established in the ground for good,the chances are low that BSV will be awaken and start expressing itself and disease symptoms appear. BSV usually awakes following stress yet there are healthy mats in various gardens that are many years old and have seen many winters and other possible stressors...
If you want,post clear pictures of the new leafs of your Mysore and the patterns and post a few leaf underside pictures opposite with the leaf lighted from the sun above to reveal the patterns.
