Good to hear you are very pleased with your new acquisition. G Pro is a outstanding mouse.
Now imagine this user experience by paying about half of its price and with a very flexible and thinner rubber cable,
well that's what G203 gives you out of the box.
That's why we keep saying like broken record G203 is the best mouse bang for buck you can get for XIM.
G Pro sensor is the best, if you can get one on sale go over vs G203 anyday.
Using a lightweight, better fit for you hand size is always another good improvement, that is what is giving you the feeling of "pointing with your finger at objects".
Bigger mice are a "size-to-fits-all" approach, no the best for an aiming device.
IMO Ventus R has a superior shape than G Pro/G203 is like having a small FK2 (FK3), it has a great sensor PMW3310 does the job.
