If your slice became increasingly bad, then that is wholly down to you, no club will fix that.I have just sold my 3 month old 10.5deg Taylormade Burner 2.0 driver after developing an increasingly bad slice,
Stay well clear of anything with Titleist in the name, not by a long way a club high handicappers should be fiddling with.
If slicing is your main issue, then buy something with draw bias built in, Callaway usually do a good range.
Adjustable heads are for fine tuning, not major swing fault corrections, and are liable to give you more hassle in the long run if you don;t know what your fault actually is.
