Bt Broadband Unlimited Good/safe For Torrenting?

[Xirix]

I'm on Sky Unlimited at the moment, I might have to change to BT Unlimited, the website says it doesn't throttle at all, and I always use peerblock when I use torrents, but I was hoping there was anyone on here currently on 'BT Unlimited Broadband' who could tell me if it's any good, have you ever gotten speed throttled, or letters sent?

 

Thanks
