Daisy Wide vs narrow frame Daisy's.

I've become somewhat fascinated by Daisy lever action BB guns and have been slowly building up a Red Ryder. I'm just wondering if there's any performance difference between the two other than the width of the frame itself. A wide frame would be much easier to make a good looking stock for, as it doesn't have to shrink down to tiny proportions near the trigger.

My goal is to build a good looking repeater that shoots close to 400 fps and is as accurate as possible without going the 499b muzzle loading route.
 
I think the 99 came with both bodies; the later model had a wide body. The shot tube also changed.I think today I will make some modifications to my 99. I bought the larger dia. air tube and stronger spring. (y)
I've got a 7/64" air tube and a Cobalt327 spring on the way for my Red Ryder. I've also installed a larger hoop lever and a peep sight to it. I'm thinking that it might make more sense to search out an old 99 or something similar before putting more money into it, but a nice thing about these Daisy's is that the amount of money spent is pretty trivial compared to most airgun purchases.
