Harpe Ace Series

Try out the Asus harpe. It's on sale right now and a fantastic mouse that can be used with all grips. I agree, the coating on the super light and damn near every Logitech mouse is slippery. I get sweaty hands as well. I was tired of it so I got a sleeve that also covers my palm (I know it's dumb) but it works wonders.

Superstrike is a safe shape but it doesn’t have the rear hump that some more specialty mice have Viper v3 pro is another safe shape, here are a few more with progressively more back hump Endgame xm2w  Lamzu Atlantis / Maya X Asus Harpe Ace I (II has less hump) Pulsar X2H (this is probably too small)

I have similar sized hands to you, it’s been a nightmare and a half to find a mouse that fits the hands properly. I have bounced back and forth between the Logitech G502X and the Asus ROG Harpe. Logitech is better for a palm grip. The asus is better for fingertip and claw grip. Found the asus mouse to be more comfortable and lighter.

My recent experience - purchased and tried 10+ mouses in October: Rog Ace Aim, Rog Gladius 3, Pulsar x2h, Pulsar x3, Zowie ZA13 DW, Teevolution Terra Pro, Scyrox v8, DAV3 Hyperspeed and DAV4 Pro. The most anticipated one was the Terra, seconded by the Zowie. Ended up only keeping the two DAVs. Don't need two but can't decide which one to give up. In my view they are miles better than the others I tried.

If you're going to be putting lots of hours on the mouse, wouldn't recommend the Basilisk. I'm on my 4th one in 5 years because the rubber grip area where the thumb sits under the M4/M5 buttons keeps rubbing thin until eventually it just wears away. 2nd one the scroll wheel material separated so it was just spinning independently of the wheel. Mouse left and right click buttons are also a bit wobbly. Switched to an Asus Harpe Ace Extreme and very happy with it. Really nice clicks, ultralight and feels good in the hand.

+1 for the xm2, an absolute beast of a mouse. Def have the ace 2, is it similar to the xm2?

Not trying to be insensitive, but do you have Marfan Syndrome? On the mouse front, I do recommend checking out the ROG Harpe Ace, it's a little long for most folks so it might be suitable for you. Best of luck!
