I am looking for new pedals.
I did some research and it looks like CST and ECCI are the best options out there.
I have no experience with neither of them.
They are a little expensive though so , are they really much better than clubsport pedals and worth to pay the amount of many?
If yes then which one i should choose?
If someone had them before and can give me some advice i would appreciate.

ECCI I'd imagine would be even better quality. According to the pros, but the club sports are pretty darn good. There first run had some issues, but the newer style are holding up nice.

Are they load cell and have you used load cell pedals before?

Yes Aaron they have.
I have been using clubsport pedals for about 5 months now
but i heard the load cell on the other pedals is better quality and you getting better feeling while braking but i dont know that for sure because i have never try them.
The question is they cost a lot more than clubsport pedals so i would like to know whats the advantage or is just waste of many. If they just look better i am going to stay with clubsport

You could upgrade the load cell in the Clubsports couldn't you? That may help and not break the bank.
IRacing has a massively big hardware forum that gets Tons! of daily activity and I have read many pedal threads lately since I am upgrading soon and have seen almost nothing but excellent reviews for the CSTs.

I don't want you any faster though so I do have a momo red I would like to sell you :)

Haha:)When i had momo i never finish the race so im not that talented like you:) Ryan i dont know if i can upgrade load cell in clubsport pedals but i will take a look at it.
I heard somewhere that clubsport pedals have a cheap load cell but i dont really know what that means because i never use other pedals
