Someone had expressed an interest in a comparison of these two. Here ya go:
PMBs, UST Tour Weight (110g) S, standard length.
870ti, Mitsubishi Adams (55g) R, +1/2" length.
This looked to be an interesting comparison. The HiCor 870ti with lighter shafts and +1/2" versus the PMBs with their stronger lofts (2-3* stronger). I've had a set of the 870ti back in 2014, loved them, wasn't a fan of the feel (with DG300 steel shafts then). My biggest issue then was the height of the short irons, they seemed to go straight up.
The PMBs had just beaten out the 575mmc (I wouldn't say beaten out, they were both great, I just like the gapping of the PMBs better). But this set of 870ti showed up on ebay and I thought I'd take another look. Kudos to the seller, this is a fabulous looking 870ti set.
I've gotten a couple of launch monitor sessions in, and here's the averages.
4 iron: PMB (21) 192 yds, 870ti (23) 190 yds.
7 iron: PMB (31) 159 yds, 870ti (34) 157 yds.
9 iron: PMB (40) 139 yds, 870ti (43) 124 yds.
With the 55gm shafts, the 870ti short irons went insanely high (5.5 higher launch angle for a 3 loft difference). The feel of the 870ti is muted nicely by the graphite shafts, they almost feel normal now. The longer clubs, not much difference noted in length, but the ball flight again is higher.
I'm already a high ball hitter, so the 870ti may be too extreme for me. But man, those are some of the coolest looking clubheads. The PMBs have no such wow factor. But there is no denying that the PMB flat out perform.
I still want to put the 870ti in play on the course, see if the launch monitor readings equate to real play.
