I would go with the ping g5 hybrid. Tour Edge Irons.
Have you tried a taylormade driver?
They are nice, and if you slice the ball, you can change your ball flight with the MWT. Then when you are at the driving range, you can change it back to normal to fix it. They are also long and straight.
If you really like the Big Bertha then I would stick with it, it is a nice driver.
The taylormade is just my personal oppinion.
I would also try different wedges. That is a great set for $80, but I would try some titleist vokey wedges, or pings, taylormades, or callaways. You can get them all for around 50 dollars on ebay
