Cold rolled steel rails question. No more 10% discount < 1/yr. on PBB

I was going to order the precision ground rails from TM, but when I called they no longer give the 10% discount to PBB members who have less then 1/year on the forum. Kinda funny because I have already spent almost $3k with them over the last couple of months and I received the discount. I understand if I never purchased from them before, but I feel I should have been "grandfathered". Also, I understand if this was my first purchase as some people probably joined PBB just for the discount and never posted on the forum. I am an active forum participant. The rails were costly, but I knew they would be perfectly square. I was hesitant on spending that kind of money at the moment, but I think the discount would have persuaded me to do it when I was on the phone with Brook.

So, I ended up ordering cold rolled steel for my rails. I knew the tolerences were better compared to the hot rolled I had on there from the PO. I replaced the rails because the hot rolled warpage was causing my machine to bind a bit.

The cold rolled came in and there is also some warpage. Again, I understand these are not "precision ground" rails so there not going to be perfect, but they are better then my hot rolled rails. Once I bolt this thing on the table, do you guys think I will be able to give it enough "oomp" while tightening down the bolts to make it straight? What experiences have you guys had?

1/8" over 8 ft, you can probably get it within 1/16". Take the straighter of the 2 and use it as your guide rail, and the other as the support rail. Use a string to check how straight they actually are.
