I think it would even out somewhat, but it's something I didn't think about actually!
Mmm, it may all just be relative actually, the larger turbo will probably be giving higher compression anyway so a greater force back onto the turbine, despite the larger inertia i imagine it would be somewhat similar to the small turbine/low boost.

Good food for though though, good thread!
