Amazing collection. You're missing a 2014 PS90, though I guess that's why you have an extra 2013.
It's sad that it never saw any TV time due to his injured season and switch to the larger 97. Because the 2014 Pro Staff 90 was easily the best version of the 90. It took them almost a decade, but with the 2014, they finally nailed the feel of the 6.0 85 into the frame of the 90.
