thequickbrownfoxjumpedoverthelazydog • Apr 8, 2019 I have a 6 1/2 AL and may go to a 5G soon.545 bore or something like that Comments [user=30872122]THADDEUS HENDERSON[/user] In my beginner year I used 2.5 AL but now that I have a step up t-bone I use 5G [user=26824076]thomas117[/user] 52d for euph but a deeper for bass trombone and a 48 for my tenor [user=27074618]IVoteTheGoat[/user] I'm currently on a Bach 4G moving to a Denis Wick 3AL. [user=30507757]Croatian Cowboy[/user] It varies. During marching season, in which I play baritone, I prefer a 48L (Yamaha), for Euph I typically just use a standard 51D (Schilke), and for bass bone I use both a Shilke 59 and Bach 4G, the former of which I tend to use more for jazz band since I'm hardly ever below the staff in those charts. In the end, for the most part, it comes down to personal preference and how the piece feels to you; how is the air flow, are you centering notes easily, what is your embouchure like, etc. etc. I'd say the 5G is definitely a smarter move as apposed to the 6.5 [user=26394441]Tromby II[/user] My brother is a band director, and my other brother plays trombone as well, and both say that 5G is much better than 6 1/2 AL for older players because it's more mature. I have both, but I prefer the 5G because after I've been playing for a really long time, the 6 1/2 AL hurts my teeth (odd but it happens). So, I'd recommend using a 5G. [user=28640043]BGray0312[/user] I started on a 5g and I've been playing on it for 8 years, but I wanted to try out some other options so I'm waiting for my Denis Wick 4BL to come in soon.
