M12/8 Monk/Fighter leveling

[AuraSeeker]

I had bought an Otto's box the last day they had them in the DDO Store and decided to bump my Monk up from 4 to 20. As I had already decided what he would be, I leveled him as the title says, using Khopeshes and TWF with the Kensei tree. However, the novice in me has finally learned his mistake, in that I just randomly chose what each level would be, instead of planning it out, so now I will need to LR a few times to get the leveling right, and that's where my question is. How do you decide, if or when you multiclass, which level will go to which class, and is there a good strategy for Monk/Fighter levels? He's a Dragonmarked human on his first life, and I don't think I will TR him, or at least not for a while. I'll edit this post later with his stats.

Thanks in advance for the help. :3

How do you decide, if or when you multiclass, which level will go to which class

I use this: http://www.rjcyberware.com/DDO/ Helps you figure out which order of levels will allow you to take the feats you want, waste as little feats as possible on having to take things you don't want, how much starting stats you need to be able to take feats in time, etc.

Even for builds that I think I have 100% figured out in my head, I still put them through the planner just in case.
