Never really used a Thriver, although I gamed the higher-lofted options for years once PING came out with a 13* driver.
My current setup is a Callaway 10.5º set to plus 1 degree, otherwise neutral weight settings. It seems to work no different for me.
PS - I also have the Callaway Mini Driver in the bag, set to 16º for our longer par3's on windy days. That's obviously an option on the shorter par4's off the tee as well, providing the wind isn't a factor. It's actually a versatile club that can fit a myriad of needs, and can be used from a fluffy lie in the rough when the ball is sitting up for the longer approach shots. From tight fairway lies - it's all about your angle of approach and your ability to pick the ball without taking much of a divot. My swing plane is steeper than shallow, so I only use it when the situation allows.
