I've picked up some stuff to try, not sure if I'll keep it all:
Cleveland UHX irons. Might put some graphite in these and give 'em a go to see if they can kick out my Steelhead XR Pros with PX.
Cally Epic Max LS driver. Been playing a Rogue SZ for a few years, and last year I picked up a Mavrik to see if it could kick the Rogue to the curb. It might have been slightly better for me, but not noticeably so I got rid of it and will try the Epic.
Cleveland CBX2 54* and CBX Full Face 58* wedges. Taking on the stalwart Cally X Forged that have been in my bag since, forever.
Still thinking about a putter to challenge the Yes! Valerie mallet that has been around forever as well...
