PS1620 demo was 323 g, 32.6 cm, 329 sw (avg 329, 328, 330) - 16g Xalt liked it so much I nabbed
@SabreCheetah9 's off the classifieds, great seller btw
PS1620 used was 321 g, 32.6 cm, 330.6 (avg 332, 330, 330, 331, 330) w/overgrip - 16g Multifeel/16g Revolve so stoked that this is so similar to the demo I had (interesting to note that the shop the seller bought it from measured it with the card in at 321 sw, so maybe +10 strung? haha)
Anything below 325 sw seems below the average. In compiling the collection of reported sw below, I noticed a couple of comments saying how clubby it was for those that had 335+ sw, but also several comments that mirrored my own experience from those with <= 330 sw that it was surprisingly whippy.
On a side note, stringing the 1620 was a dream. The construction of the grommets leaves little gaps for you to thread through when you have blocked holes; I'm thinking I didn't even need to string the first couple crosses before finishing the mains. Spend most of my time stringing blades and fx 500 and not having to dick around with pushing through blocked holes with that lower cross was a nice change of pace.
