Difference between installing Roundwounds and Flatwounds?

I posted this thread in the wrong forum, i apologize

First off, i want to say that i tried to search threads with this topic but i'm still not very sure on what i should do when installing Flatwounds, so i made this thread.
When i install roundwounds, i cut the tuning post part of the string by a few inches so that i don't end up with too many windings and then i bend the very end of the string to make sure that the windings don't unwind or that the inner core does not slip, then i try to put the string, wind it around the tuning post and tune to pitch. I tried doing the exact same with the flatwounds that i got, but i got some bad results. The A string sounds rather dull compared to the other strings and i think it might be due to me installing these strings badly. My main question is: What do i have to do with the Flatwound strings when i install them? Is it required that i bend the very end of the string with the flatwounds, or do i just cut what is not needed and put the string without having to bend the very end? Also, when i put flatwounds, i learned this other problem known as the "twisted string". What precautions do i have to take to prevent twisted strings?
Also, this is the first time that i encounter those coloured silk parts in both ends of the strings. What do i need to know about them? I have installed Ernie Ball Cobalt Flatwounds on an Ibanez SR500, btw.
That's all, thanks for reading.

 

I don't know, the rest of the strings sound just as fine as i want them. However the A string itself sounds semi-dead and i do not like that. Are flatwounds the strings that have a hex core?

 

Oh my, sorry my mistake! I want to put the thread on "strings" but my mind was off and i accidentaly put it on basses... how do i change that?

 

Yes. From 40-95 to 45-100

 

it looks fine. i didn't have any difficulty fitting the string in the nut slot and it's not positioned differently than the rest of the strings.

 

yes, i've only made things worse by slightly tearing the silk wrap...

 

that's the bend trick that i mentioned too, right? i did that with the flatwounds that i installed

 

Seriously though, do i also have to do that trick to flatwounds too? Even with the silk wraps? I thought i made a big mistake by doing that..

 

Putting these strings on was absolute hell. I've never ever had a nice, calm, easy and pleasant time while restringing my bass. It's one of the worst things ever.
