Ever since I played RDM, I always avoid hardcasting VerAero and VerThunder. I only use them through duelcast, after casting Jolt II or Impact (or after the procs). But recently, I've been finding that some players have hardcasted both these spells. Should I ever hardcast them or just keep doing what I've been doing

Also, it's common knowledge among RDMs that you need at least 80 Black & White mana to use the full enhanced melee combo. But I prefer waiting, until I have them both at 100. Doing this gives me access to both VerFlare and VerHoly, after Enhanced Redoublement. How effective is this? I appreciate any responses.
