I'm still trying to decide whether to put in the high capacity rad or not. I posted here asking if it was worth it and got a mixed response. Its only a $300 difference so I will probably just do it.

I am just waiting for my daily to come back from the body shop (dump truck lost it's load on the frwy and pelted me with rocks) so I can take the Z in.
Be aware that some high capacity radiator is good at keeping the motor cool at sustained high speed (as in racing) but may not help much in low speed street driving because at low speed you are relying on rad fans. Rad fans may not be able to pull sufficient air through thicker radiator.
I recall seeing a thread discussing merits and demerits between Dewitt and Fluidyne radiators. If I remember (I may have this backwards) correct, Fluidyne seemed to be the better choice for street use.
I replaced mine with factory radiator that came out of a 95 with a few thousand miles from a forum member. He was extremely generous and let me have it for $50 (you know who you are...Thanks!). Cooling has not been a issue ever since.
Also, I thought about intake screen but when I pulled the old rad, it was obvious that it wasn't just small debris but amount of fine particles that came out between fins were quite a bit. I can't see any type of screen that could allow air and yet keep fine particulate from collecting between rad fins.

I have to agree about the HD radiator. When I did mine I put an OEM back in and no problems. Also regarding the screen, I did that when I had my radiator out. You wouldn't believe how small of particals that it stops from going up into your radiator. Even if you are not mechanically inclined this can be done with very little effort and most of the tools you would have laying around your house. Try it - you won't be disappointed
Good luck and save some money with the OEM radiator More Mods...

Correct sand, dirt and slit wont be blocked, but the major debries like leaves, bags, straws and everything else will.

I hear you.
I have been known to make some wild evasive action to maneuver around crap blown around in front of me.
