Given the lack of enthusiasm for the new Max spin wedges (not a single thread yet in the Equipment section, and not many reviews), WGT might want to spark some interest with another free rental weekend. You never know, they might be quite useful for chopping out of rough onto a downslope, or getting out of 30/40% bunkers with some element of control. But, already having the Clevelands, I wouldn't want to waste any rental credits finding out.
This would also provide an opportunity for R11 iron users to try the L79 Bladez. Clearly they aren't as good, but perhaps a free rental weekend might boost sales to higher level players who want to try and level their meter speeds.
