When I first got my bravo I spent the first 2 weeks just making onies with scrap 9.5 and 12 mm blow tubes (mostly 9.5) because there wasn't any 25mm tube in the shop. I really think it helped me prepare for using the 25mm. I got much better at opening a small tube, and learning to control my flame setting on the new torch. It gave me some experience flaring the tube and obviously welding them. I made about 40 onies probably before the glass order got in and I started trying spoons. I also got my foot pedal right about the time I started making spoons which was awesome! I love being able to just tap my foot and get my outer fire.
