I've used 23g since forever ago and got used to them. But recently bought some 25g from ar-r and I couldn't be happier. For some reason I feel there is less pip. I don't feel the pin going in at all. Really like that I switched.
The only draw back, if it is a drawback, is that I can't plunge as quickly as a 23g pin, but that might be a good thing. With the 25g pins, its a nice slow plunge. Maybe that helped reduce my pip too.
Overall, I'm a happy camper.
