Hi Chris,

I have done the same but I scan the film instead of making large prints. 
Its a great way to see your film highly magnified! Of course if you don't 
have a scanner your way of making large prints will just as surely tell 
the story.

I've used the 24 enough and seen the results often enough that I know it 
well. 
The sharpness at the plane of focus at f4-f8 is spectacular.

I think the 15 Heliar is similar in that it seems best at f5.6 and f8 but 
I have not used it enough to really know it yet.
