I use a #30 too, but I sometimes get tired because of the
thinckness of it and wish I had a slimmer handpiece. Haven’t
heard anyone else coment on this aspect yet.
I lke the Faro (10D) handpiece without the duplex spring- I have
2 of them and my parttime helpers grab the second one for their
own use. The drawback is that it takes only 3/32" shank burs- so
I plan around it. I had a Techno, and one of my studio mates has
settled on that design- of the two the Faro is slimmer and the
collet needs no adjustment- though occasional lubrication helps.
