2" Nosepiece

I use a 10" LX200, f/6.3 reducer, Scopestuff 10:1 focuser, then 2"->1 1/4" eyepiece adapter over the 1 1/4" t-adapter & t-ring to a Canon 50D DSLR. Would a full 2" nosepiece do anything for me? More light? Less vignetting? Stronger? One less thing to put together?

I think the 2" would have less vignetting than the 1.25", and is one less thing to attach. I sort of guessing, as I haven't compared one vs. the other. I use a 2" on my DSLR.
