I've worn both Spidi gloves & have crashed @ speed (80-85 mph) in the Race Vent... no problemo. No bruising, scrapes, cuts, or other injuries. The gloves were sewage after the fall, but hey --- they did their job to a T.
I've also have Spidi 2-pc leathers and they did rather well in the same get-off. Really very minor scuffing that I was able to tidy up afterwards so that you hardly even notice. I've also worn Spidi XPD boots with no complaints what so ever. And... I also have a Spidi Mask textile jacket that wears like iron.
I have owned A* boots & gloves and have been happy with them, but I probably could/would be just as happy with another top brand.
I think you'd be well satisfied with any of the gloves you mentioned.
Cheers
