Jeff:
As Matt said, look at that bubble EVERY shot on the 3D course. Crazy sidehills, etc......where you have bad footing.........what feels right isn't always so. Trust me on this. It should be part of your shot sequence. This is a big part of why I really prefer a sight with a larger bubble too, because after the initial check on that bubble I like to be able to see it subconsciously through peripheral vision as I'm aiming. If something doesn't feel perfect I can know where that bubble is without breaking concentration from the target if I have a large bubble.
You need to convince the shop to buy a quality 3rd axis vise. We have a Medicine Stone at the shop I help at, and I'm buying one for my house as well. They are a bit expensive, but are the best designed unit out there I've seen yet. I also much prefer the HTM levels kit over the Medicine Stone levels, because the HTM's will allow you to get the bow in the vise with your string completely level on 2x planes without moving the level, I'm yet to see another stringlevel out there that has a bubble for 2x planes.
Medicine Stone Bow Vise:
One of these days I will take a quick video to share on youtube of how I set 3rd axis. I plan to have a 3D specific bow in the next 3 weeks or so and when I get it, I will take a video when I set it and share with everyone. I really prefer to do it on the bow, as compared to a lot of guys have a jig setup to test 3rd axis with the sight off the bow, and if there is any variance between the riser and string's plane then you have an issue (I've seen this personally).
***Edit*** - To add to this, once I've set it on the vise, I will go outside and shoot a few groups at themaximum distance I've got a pin for (47 yards)at extreme angles to see what happens just to check everything. Every time I've set it on the Medicine Stone though, I've never had a problem once checking. I would still recommend to do this every time.
3rd plane sight adjustment
..........would you rather trust the bow is set up properly and know that it was YOU that missed the 10ring by 1" to the right on a downhill shot? Or would you rather wonder if it was you or the bow?
