2	Ideal by 60% of measurements		S/M - M	108	66	63	1.72	39		<90	-	3360+		Yes	Yes	Yes	Ergo	115mm seems like a good length with a grip width of 63mm and a height of around 40mm.
3	Logitech G9 (precision)		Medium	110	70	63	1.75	39		156	-	Laser POS		Yes	Left Only	Yes	Ergo?	Former mouse. Fingers rest just before the end, width is pretty much perfect (~63cm where I actually grab it), as is the height. Way too heavy.

4	Logitech G Pro Wireless	1	Medium-Large	125	64	59	2.12	40	125	80	$150.00	Hero		Yes	Yes	Yes	Ambi	Might be a bit long, but everything else looks perfect. Wish it was an Ergo, though.
5	Cooler Master MM711	2	Small	115	63	55	2.1	38	115	60	$21.99	3389	Back	Yes	Yes	No	Ambi
6	Cooler Master MasterMouse S	3	Small	117	64	56	2.09	38	116	89		3330	Back	Yes	No	No	Ambi	Pro: Sensor is good, relatively light. Con: Had to remove 13g weight on the inside. Case known scratches against mouse pad. Cheap construction. Narrower around thumb/pinky than I was used to, but it's growing on me. New versions will be much better.
7	HyperX Pulsefire Surge	4	Medium-Large	120	63	59	2.04	41	120	100	$70.00	3389		Yes	No	No	Ambi
8	Roccat Kone Pure Owl-Eye	5	Small-Medium	115	70	58	1.99	39	118	88	$50.00	3361		No	No	No	Ergo	Pro: Proportions seems good on paper, but I'd have to hold it in my hand to know for sure due to the shape. Stores settings on the mouse. Con: I might have to adjust my grip due to the buttons wrapping over the edges. No comfort curves on buttons. Stiff cable (Grip width between 56-58)
9	Zowie EC2-B	6	Medium	120	61	56	2.15	40	121	90	$70.00	3360		Yes	No	No	Ergo	Pro: Highly regarded shape. Excellent Sensor. Con: Clicks are stiff, which might be a problem. DPI steps are preset, which is annoying. See old EC2-A review for a review of the shape. Might be too narrow (RJN measurments differ from advertised grip width)
10	Ninox Astrum	7	Large	133	70	58	2.3	40	124	80	$90.00	3360		No	Yes	Yes	Ergo	Grip width is a guess
11	Logitech G403	8	Large	124	68	60	2.07	43	102	87	$46.00	3366		Yes	Yes	Yes	Ergo	Pro: Excellent clicks, MUCH easier to pick up than the Rival 600. Stores settings on the mouse. Con: A bit tall. I REALLY wish they made a shorter version of this. It would be my first choice if it was under 40mm tall. A little front heavy (extra 10g weight balances). Probably too big.
12	Finalmouse Ultralight Pro	9	Large	127	61	60	2.12	39	128	67	$70.00	3360		Yes	Yes	No	Ambi	Pro: Lightest mouse around (67g), it's flatter and more narrow than the Rival 600, so maybe okay? Width seems good on paper. Con: Company has had QC issues in the past. Probably too long. No ledge for ring finger.
13	Nixeus Revel	10	Medium	125	68	57	2.2	39	117	85	$34.99	3360		No	No	No	Ambi	Pro: Super inexpensive (build quality?). Omron switches. Con: A little long, but a good height and width. No comfort grooves :-/
14	Mionix Castor	11	Medium	122	70	55	2.22	40	110	94	$60.00	3310		Yes	No	Yes	Ergo?	Pro: Ledge on right side of right mouse button. Neutral: On the wider side, which could be good unless it makes the middle click hard to click without changing the grip. Con: Sensor could spin out. Shape on the right might be odd. Some QC issues.
15	Dream Machines DM1 Pro S	12	Medium	126	68	56	2.25	39	112	85	$95.00	3360		No	No	No	Ambi	Pro: One of the top recommendations from Zy. Con: A little on the larger side, but the proper height. No comfort grooves. Expensive.
16	Ninox Venator	13	Small-Medium	122	62	54	2.26	40	117	78	$55.00	3360		Yes	No	No	Ambi	Con: Questionable Build Quality. Updated Model: https://youtu.be/CPQiHqh9aIE
17	Zowie FK2	14	Small	124	58	54	2.3	36	112	85	$60.00	3310		Yes	No	Yes	Ambi	Pro: Zy's current favorite, possibly best for fingertip. Con: Might be too long and narrow, but the thinnest of the mice I've found. Sensor could spin out, stiff clicks, buttons on the right side would be annoying.
18	Logitech G Pro	15	Small	117	62	55	2.13	38	100	83	$47.00	3366		Yes	Yes	Yes	Ambi	Pro: Length is about right, excellent buttons and sensor. Stores settings on the mouse. Con: Width might make it feel cramped, especially with the lower than average height. Probably too small and could cause issues with my RSI.
19	Rival 600	16	Large	131	62	62	2.12	43	130	96	$80.00	3360		Yes	Yes	No	Ergo	Pro: Good build quality, excellent sensor. Con: Too long, and the right front side is very hard to pick up. Middle click hard to reach without changing grip. Left/Right clicks are hard to jitter click.
