yeah straight bcaa's taste like rubbish...my pre/during workout one is flavoured (purple wrathe brand)
and the post workout one i have with protein and carbs so cant taste it that much, though you can still taste the crapness a little bit lol
P.S. roman deadlifts are the bomb, do a few sets and ur hamstrings will be torn for a good couple of days
best tip is to test and adjust, u really have to feel your way through the exercise and focus on using ur hamies, is really good for ur grip too
