Technical suggestions needed - Which tweeters?

OK, I ordered 4 of the RDO-194's to replace 2 per unit in my SDS-SRS's. If everything goes well, I may order four more,but for now, I'm gonna try half of them.
So my question is: Which tweeters? I've seen the xover schematics for the 4 tw per unit, but I'm a computer geek, not an EE, so it doesn't mean much.
I did try this: Took a piece of vacuum hose and stuck it in one ear, then listened to each of the tweeters individually. I cannot judge the frequency rolloff very well, the there was a pretty dramatic difference in the volumes. The LOUDEST tweeter is the third down from the top. The second loudest was the one on the top. The other two were less prominent.
Does this pattern sound right? Or would it be source dependent? At this time, it's sounding like TW(1) and TW(3) are the ones I'm gonna replace.
Thoughts? Experiences?
BTW, if you get and odd noise in your car engine and can't locate it, try the vacuum hose method. Old trick I learned from the best machinist I ever knew, long time ago!

I only have one thought and I'm not trying to be a smarta** about it either but why not just replace all eight at the same time and be done with it. I can't see any real sonic benifit to doing them one half at a time.
Maybe someone else has already been down this path??? -
Tweeters don't grow on trees...
I ordered four. That way, I can experiment with doing all of them in one unit, and doing an A/B comparison, or half of them in each unit.
I may end up very happy with only two per unit replaced. -
I can tell you from experience that sticking a new tweeter or two in with the old ones doesn't sound too good and will not give you a handle on what they really sound like. If you want to play around, do all 4 in one speaker and A/B them left and right. That will tell you the most.Political Correctness'.........defined

OK, I'm waitin on the mailman every day, but nothin yet...

But I have another question that goes allong with the other one.
Assuming I get the four which is what I ordered, and replace two per unit, here goes, I'm gettin to it, is there any way or does anybody have any ideas about testing the 8 SL2000's and picking the absolute, best 4 to keep?
Or are they pretty much the same?
