John, I am sure the stringwalkers will be happy to have another shooter in the flock

Maybe Borders would not mind if we talked just a bit about stringwalking since I think sooner or later the best stringwalkers are going to find out about Borders TXG's

Since you have been introduced to the basics you have an idea about the process. The thing is you are asking a lot out of you limbs and a ton of forgiveness out of your bow and arrow tune. From a short ranges crawl, you can lose 4 to 6 fps off the speed of an arrow compared to the speed you would get if you shot the arrow with your standard three under (point on) draw and release. This means you have to tune for an arrow spine in the middle or low side of the spine range (at least that is best for me). If you tune an arrow in the mid spine range and tune it for mid range let's say 40 yds, your arrow is going to shoot stiff at shorter ranges and maybe a tiny bit soft in spine at the longer ranges. After a lot of fiddling and practice you can learn to take the left/right movement out with pre-calculated plunger spring tension. Of course you can also just aim off the left or right side of the string if you wink the string on the arrow tip when aiming.
I have had several 3D/hunting bows set up to shoot off the shelf while string walking. For me the groups held up to 50 or so yds. I never got the shelf tuned good enough to shoot 60 to 80 yd groups off the shelf that were as good as my groups off a magnetic flipper. That said I can tell ya there are some barebow shooters around that can shoot 60yd groups off the shelf in the 10" range. They must have the smoothest release know to man

alas I don't and need all the help I can get from my equipment.
The bad part of stringwalking in the States is the lack of competiton. I haven't got to shoot in Europe yet but understand there are many more string walkers there.
If you decide to give stringwalking a go let us know about your progress and what you learn. Stringwalking is a discipline for tinkerers. You will never stop experimenting, testing, and learning. There has never been more fertile time for stringwalkers. So much new stuff
