Ah yes, try to press one CTRL and then the other.
It can't be that uncomfortable, unless you're trying to hold both of them with one hand!
Use your left thumb for the left side (and keep your middle finger above the ESC key) and use your right index finger for the other CTRL which should allow your right middle & ring finger to rest over the arrows so you can adjust the aim. If that doesn't improve comfort, then either our keyboards are set up differently or my fingers are longer. I hope you do think it's worth another try this way, because it does seem like the bottles charge faster and who doesn't want that?!?
Also note (for anyone else who is going to try it) if you let go of just one CTRL key - you will squirt (ready or not!) so, try not to let go until you are ready or unless you have to (Fore!).
