I have no problems with hspl. Been using hspl on all my devices for years without problems. But if you flash a custom rom once or twice every few months there is no use for hspl, and temp sollution like rspl is ok.
But when you cook, and test roms very often, hspl is pretty essential (for me) If I had to flash rspl every time I was to test roms I would go crazy
I meant it for noobs and newbies anyway.
