I had a club of some kind that was 75%... something. Can't remember... see, that was the day I first beat Ultimate Falz, and then the cube froze in the middle of the credits. :ermm:
My BEST percents, as in on weapons that I actually use or have used... hmm: (these aren't necessarily HIGH, but are good IMO considering what weapon they're on)
15% Beast, 35% Hit on Frozen Shooter (used by my RAmar)
20% Beast, 20% Machine on Frozen Shooter (used by my RAmarl)
10% Native, 10% Hit on God Hand (used by my HUmar, but he got it from SoaB so I couldn't argue the percents)
30% Native, 15% Dark on Demolition Comet (used by my HUcast)
30% Native, 20% Dark, 15% hit on Red Handgun (used by my HUcast)
[Some other percents], 25% hit on a Gush Vulcan (used by my HUcast... I give him all the hit weapons, within reason)
50% Dark, 25% hit on Yamato (once used by my HUcast... put this one away when I got him the Demo Comet

)
45% Native, 5% Beast, 5% Dark on a Diska of Braveman (occasionally used by my RAmar... yeah, it was the first one I ever found, but I didn't know about percent arguing at the time :ermm: )
25% Machine, 50% Dark on a certain Justy that I've been meaning to give to my RAmar for his next Dark Falz battle...
One of the most useful non-rares I've ever used is a certain Blizzard Buster +7 with 35 hit (and a couple other 25% stats). Originally found it with my FOnewm, and I've been passing it down the line ever since; very helpful weapon for my characters in Hard mode.
