Wheels - Brand and Size Opinions

[TXSUT]

I'm looking for a bit of advice, as I'm shopping for some new wheels for my SUT. The brands I'm looking at are Weld, KMC, and Helo. What's your opinion on these brands, i.e., is one better than the other, or are they all close to equal in build quality? Any strong feelings you have that would lead me in another direction?

Secondly, I'm trying to decide between 18" and 20". Is there any off-road performance differences that I should be concerned with? I won't be doing any rock-crawling, and will be limiting myself to light-duty off-roading and muddin'.

I did search the forums, but came up dry. Please feel free to link me up to any previous such discussions, and flame me in the process for being so inept.

Thanks,

Pete
