I am currently running a TST, Edge EZ stack on my 06. This is the same stack I had on my 05. I really like this combo but I've heard alot about the Smarty. Does it stack well with the TST and what are the advantages over the Edge; power wise? I like being able to just flip a switch up and down on the EZ to adjust power rather than waiting for a download. That's one of the main reasons I chose the TST also. I like having the power right away if I want. Also my TST is a early 04. 5 model serial number in the 2000's. It looks like there are some new things on the TST now. Would I gain anything by getting a new TST and which one early twins or late twins? Any input on the best way to go would be great. Thanks
