I have one and Ive never had my hub-stacks fall off even when dropped, they stay on pretty well. Compared to a Yo Yo with no hub-stacks they do make some noise, but its not anything too loud. Ive never owned or thrown a DM so I can’t compare the noise.
I’m not a big fan of pull starts, I can easily get a 1:30 on a decent pull start but I can get WAY more if I just throw the Yo Yo.
BTW I really don’t like the PGM prob my least thrown yo-yo.
Like Zombieheadshot said, hub-stacks have never fallen off on my end, and yes they do make a bit of noise, but for one who doesn’t like all the noise, it’s not something a bearing cleaning couldn’t fix up. I’ve thrown a DM once or twice, it was a friends so the noise of my PGM was a bit louder, but his bearings were recently cleaned when I threw it, so that most likely had something to do with it. Pull starts, I’ve done a few, but in my opinion since you can’t really get a good enough grip to make a longer spin time, actually throwing is better? I recently removed my hub-stacks though and replaced the axle with a m4 bolt/nut and everything plays out wonderfully on my end.
Not to get off topic, but yeah, I’ve had the PGM for a good 2-3 months, and not exactly in the position to spend a few bucks on a new throw, and the hubs for the axle was partially stripped (difficulty putting the two halves together, the axle would slip). I enjoyed having the stacks in the beginning, but like a few others, they grew old and really held no use (opinion) other than to pull start. Figured removing them wouldn’t do no harm, and it didn’t.
Not sure why/how, but one side of the response (K-Pad) came off the third day I had it, so now I’m using hybrid (K-Pad/Silicone) and it’s been a good 3 months or so, I’ve played with it every day and I haven’t seen a loss in grip yet (Unless I’m just ignorant of when I really should replace the K-Pad, which will be with silicone so no more hybrid response). Best estimate I can give for the moment.
