I tried your suggestion, I dont notice a difference really with the masteries, but if you say its better ill take your word for it, however you were absolutely right about last whisper, its a little lower on DPS, but the added attack speed and armor pen really helps. Thanks

Cool thanks, I'll give it a shot and see if it give me any improvements :)

Good guide. I like the AD TF builds a lot more than AP, which everyone seems to be going for lately...

Only fault I find really is that you took Greed and maxed out Brute Force in your masteries, but left Alacrity at only 2/4. Since TF is somewhat reliant on his stacked deck procs, more attack speed is important, so I would suggest taking 1 out of Brute Force and 1 out of Greed to fill that up.

Other than that, I'd say go for Last Whisper before Infinity Edge since it's so much cheaper, and the 40% armor penetration is huge
