First of all I have to say that I do have a bipod on my rifle and it does get occasional use.
However, of late I've been putting some practise into shooting off short sticks kneeling - I prefer kneeling to sitting. Despite what I expected it didn't take me long to see a significant improvement in my shooting off sticks. Every time I went out stalking I put up a target and fired maybe 6 shots maximum and I'm starting to get to the point where I could take chest shots at deer off the short sticks out to around 200 yards, which is pretty much where I'd stop even with the bipod.
I also did the same with longer sticks from standing and, again, the improvement was pretty rapid and I was amazed.
The confidence you gain in being able to take such a shot off sticks means that you can shoot over undergrowth without a second thought and without having to look for a suitable rest or find a spot where you can put the bipod down. My experience is that it is rare to find yourself in a position where the only available shot is off a low bipod and I would say that since I started building my confidence in the sticks I take the majority of shots kneeling. I could probably take the bipod off the rifle now for forestry stalking but don't quite have the confidence to do that yet, however that might come soon.
The sticks, either size, are also handy when trying to walk quietly in forestry so carrying them is an advantage rather than a disadvantage. I bought my short sticks and made my long sticks from B&Q garden canes and if I was doing it again I'd make the short ones as well.
I'm guessing you probably already know this and in all probability you are a better shot off sticks than I am but I thought to give you my perspective on the matter, plus you really don't want to be carrying that porta-aim thing about with you when stalking.
