115mm of the Kone Pure
This is about the size range I prefer, I wish for something slightly smaller but I have had Pure (KPM.) I mostly like the Pure shape, except for the protrusion on the right side which interferes with my comfortable pinky placement.
imho Logitech quality has been heading in the wrong direction for several years, but even so, because of the size and current best sensors I will still suggest:
- G303 - 115mm, but is has a somewhat narrow nose which can be a problem if you rest three fingers on the buttons and wheel. The backside is too fat to be a perfect finger tip grip style. Also, it appears to be discontinued so stock may be harder to find.
- G Pro - 117mm, on the spec sheet it's narrower than G303, but the shape is so different it feels a wee bit too wide for my ideal, it's narrow enough to use, I just wish it was slightly smaller.
The Roccat wheel is better, so that will likely be a disappointing feature on the Logitech vs the one you're used to.
