Impossible Warrior - no losses?

[Zhuangzi]

Well, I must have played for 8 hours today (at least) and it has been slow going ensuring zero casualties. I am up to 58 battles without loss now, which means I got the Grand Strategy 3 medal. I finally cleared out the last guardian on Scarlet Wind, which gave me the Verona map I needed so badly. Bolo is cleared out except for about 4-5 stacks, and Rusty Anchor is less than 50% clear. But with 3800 leadership all remaining stacks are Lethal, with maybe a couple of Very Hard.

I haven't changed my team for a long time now. It works very well with the exception that I haven't found enough Royal Thorns or Paladins. I know that there will be plenty of these in Verona though.

So I've been fighting with:

63/63 Royal Snakes (the main attack unit)
35/35 Inquisitors (for rage and resurrection)
12/12 Royal Griffins (for Heavenly Guards and mopping up weak enemies)
4/10 Royal Thorns (for Thorns)
6/17 Paladins (for defense and resurrection)

The problem I have had is that with only 6 Paladins, I am doing a measly 144 hp of resurrection. Consequently there's no room for error at all. If I can fill up my Royal Thorn and Paladin stacks in Verona, I can probably mop up the small islands. First I will pick up everything I can find in Verona.

Oh, and despite zero losses, I've only got about 60,000 gold. DGD is quite right in saying that you need to use Treasure Searcher twice a turn if you possibly can. Now that the Trading skill is gone in KB:AP, gold is much scarcer on Impossible. That's a good thing - it's making it a really tough but possible challenge for me.

Question: There are 2 Red Dragons for sale on Rusty Anchor. Should I use them when I get my leadership up to 4000 or stick with the current team?

I honestly haven't had so much fun playing a game since Master of Orion 1 in 1996.
