Hi Stan!
I am aware the V16 tenor ebonite comes in different sizes to the Java/Jumbo Java - T7 to T10 - with the smallest tip being slightly larger than a T75. The Metal V16 tenor has equivalent sizes to the Java - I play a T77 in metal - just to confuse the issue.
I've not played a V16 tenor ebonite but use a V16 ebonite on alto (excellent - a 7m) and a V16 metal on tenor (also excellent - as above). I imagine it would be excellent, and the T7 and T8 are both long facing, the T9 and T10 are medium long.
Good luck, and certainly worth a try, having played the metal.
Tom
