P28's my favorite retail curve at present as well, but it really comes down to personal preference. The P28's aggressive toe rocker and loft give a lot of people trouble, causing puck flutter, and sending shots high, respectively. Both of those pain points are even worse coming from P88, as it has the flattest toe rocker and least loft of the commonly available blades. It could be a few years before P86 becomes mainstream, but it would be a safer bet than P28 for anyone coming from P88.
