Rolled roast or solid roast?

[gnubee]

I was wondering if a solid roast smoked low and slow cooks differently than a rolled roast does. I had a rolled roast stall for an incredibly long time while the solid inside round zipped right along with almost no stall. Timewise it was 1 hour and 35 minutes difference for 5 lb roasts.
