If you're going to be ripping, get a ripping chain. It depends on how much sectioning you're going to be doing, and by "sectioning" I'll read that as conventional cross-grain cutting. If it's going to be literally one or two cuts a day, it might be hard to justify a convential chain for just that, and if you're going to be ripping with that 026 it's going to need all the help it can get, as it's not a milling saw, and ripping is tough on a saw, and calls for large amounts of torque, though theoretically any saw can do it. I'd say get both types of chain, and do it right. I guess I see it as chains are cheap, and your saw will thank you if you have the right chain for the job. You'll be happier yourself as well when the job goes faster with the right chain for each respective type of cutting. If you get the ripping chain, you'll have to convert that saw (and bar if it's a roller tip) to 3/8" pitch if it isn't already, as I don't see any ripping chain in Bailey's in .325 pitch. Though someone may know of a source for ripping chain in that pitch.
And just as an aside, if you're going to be relying on a saw to rip wood on a consistent basis, you might look into another saw besides the 026. Like I mentioned above, even your Wildthing is capable of ripping, but ripping takes it's toll on a saw, and it'll be far more noticable and accellerated on a smaller saw that wasn't meant to cut like that. Just a thought.
