Rapid Fire questions

[Thorax]

I got a 360 for Christmas, and I finally worked up the nerve to mod my controller. Now I'm wondering what the differences between the sleeper mod and rapid fire mod are. At the moment the only game I have is Halo 3, but I might get COD4/5 soon. And which one will last me the longest in terms of the games blocking it (i.e. COD5's fire-rate)?

Sleeper means no extra buttons added to the controller (Looks stock and in my eyes sleeker )

This- https://acidmods.com/ShopUSA/product_info.php?products_id=58&osCsid=hdm0dbtmdp4cf1jinabbm3osl6 is a good one for you, works with COD5 and no Cap on it, halo 3, COD for Gears 1&2 and RB6.
