Been experimenting with some 315g-330g sticks over the last few months, adjusting stock weights and balances, and whilst there are some advantages in manouverability, and RHS, there really is nothing like a solid, hefty stick for getting results. Slices bite more, serves boom, volleys are rock solid, you can dominate the rallies just that bit more, generate more action and pace on the ball, as well as increasing the ability to turn defence in offense. Mixed with good, fresh poly - I use BHBR 17 - it really is just bliss. I've gone back to my 6.1 95s (350g-355g), and I'm staying there. That is all.
