Is my male too large?

[sho220]

I am new to this lovely world of ball pythons, and I have fallen in love with these creatures. I have started my collection, and I have run into a question...
I have a spider male that is at a nice, healthy 620g which seems to be normal for a male.
I also just today picked up a normal male, (verified male by myself, and my father who is a vet) and he is easily triple the weight of my spider. He doesnt seem to be fat, he is just a huge snake!

My question is, is this size healthy for a snake?
He gets around fine, just kind of worries me, especially due to future breeding plans.

What ages are we talking about here? My adult males tend to weigh about 1200-1500 grams on average.
