Hello from Austin.
The Savinelli line has the regular, KS (king size?) and EX (bigger than king size) designation on their pipes, so that might make shopping online a bit easier.
I'd say smoke what you enjoy and to heck with what others might think. I smoke large and small pipes, based on the tobacco selection and my mood.
Once you fill an EX full of a nic bomb and get nauseous from it, you'll appreciate those smaller bowls a bit more.
Easy to hold is a separate matter. You can always find larger pipes to enjoy. You don't have to fill them all the way up. Some have a massive piece of briar with a smaller than expected chamber bore, giving you some flexibility in outfitting yourself.
Sites like smokingpipes.com list dimensions on each pipe for your consideration.
What tobaccos have you been enjoying?
