'90 model handlebar advice

I bought my bike with Renthal bars already on it, but they seem to have too low of a bend and it feels like I have to lean over too much when standing. I'm somewhat of an old wuss rider, but have been doing primarily MX with the bike and am steadily catching more air. A recent endo has bent the bars so now I'm looking for advice on a better replacement. Some questions:

1.)Seems a lot of people on the board recommend the CR-high bends, are these different/better than KX-high bends?

2.)Will reversing the bar clamps on a '90 model move the bars forward more?

3.)Any opinions on using cheap steel bars? Since I've managed to ruin a set of high dollar bars already I'm thinking why not just buy steels since I could bend four sets of them for the price of new Renthals.

Any advice would be appreciated since I'm relatively clueless on what to look for, I only know that what I have now feels too low and I want whatever is best for aiding control in the air and/or while standing.

Thanks C'Dave, if you could measure them and let me/us know, that'd be great.
