My disorganized thinking on this:
One thing a lot of people don't consider with these guns is that the rubber stocks are really "grippy." Your first thought would be, "That's a good thing, right?" And it is, but with my 340PD I find that the gun recoils so quickly and violently that the grippy rubber stocks keep a hold of the skin of my hand and jerk it around in a pretty painful way. It is a lot different sensation than using rubber stocks on something like a 4-inch Model 19 or Model 29. Once you catch on to this you might like wood better... ?
These guns are so light and recoil so quickly that it is really not possible to shoot repeat shots very fast with them. In most cases you will have to adjust your grip on the gun between shots, no matter what type of stocks you are using.
I think the only way to really know what is going to work for you is buy something and give it a try. I had plenty of J-frame stocks of different types lying around when I bought my gun, and I ended up leaving the factory stocks on the 340PD (Hogue Bantams). I can handle it as-is for a couple cylinders of anything other than 158-gr. magnums. 125 grainers are pretty tame, comparatively, and even Winchester Silvertips (145 gr.) are not too bad. Beyond that, I didn't think any particular type of stocks (unless they are so big that they are impractical on the gun) are going to make a drastic difference.
These guns are not really trail guns. If they are all you have, sure, why not, but if you plan to actually do some recreational shooting while your are boondocking, I would certainly take something else. They are basically city-slicker guns and are of not much use other than that.
