Mid-level spirit stones

I have a few questions about spirit stone allocating. Currently my vanguard has STR/WIS/STAM/COUNTER/BLK/DODGE. Dodge is underwhelming, but in pvp it does help vs. my opponent's vanguard since they are usually last to get hit rate stones, so if they miss, they don't get to buff themselves. Right now the dodge stones are lvl 5/6 and was wondering if I should synth them into 3, then use the 3 open slots to put in hit or agility. The only useful thing I found for those dodge stones were for espada #4 1v1.
Second, all my assaulters and supports run str or wis, agi, crit, hit, bd, and the last slot 3 of counter and 3 of stamina. As I work toward the end game, I am finding that I need to have stamina and have refined my gears into str/wis, agi, stam. Since I have stam in all equips, should I replace my counters and go straight stamina? I definately get a better boost % using stam since I have it on my gears, but would the extra hp justify not having defense against crits?
Third, I have crit stones on everyone except vanguard. Most are level 3/4 only. Should I synth them and put them on 1-2 members? I spread them out for ryoka attack and evil spirits. For pvp it doesn't seem like a good idea to spread them out since my crit on each is lower than enemy vanguard's counter rate.

IMO, having Agility on your vanguard is a waste, unless you have Toshiro.
Feel free to save your dodge stones for future Espada battles. As for now it does not hurt keeping a few on your vanguard. I suggest replacing 1 or 2 stones with Hit stones, that's IF you miss a lot.

As for Counter I'd say you have to try it out against people on YOUR server.
If you can survive the 10th skill, in PVP, go ahead and take whatever you like.
If you die I suggest you take a look at where you die from.

If you only die from Crits you take Counter.
If you die from the damage itself go with stamina.
Having both counter and stamina is great too.

Crit stones really depend on what formation/characters you are using. Rukia and Urahara do require crit stones as well as your assaulters during PVE. Once you have the 10th skill which attacks all enemies you will start noticing the crits, especially on assaulters and supporters.
