RE: tt-01 vs ta-05???
As for wich one you get regular, R, MS depends on your budget and the rules. Check out your competition as well. If you have the cash go for the MS(why not). If your on a budget you can get a regular TA05 and gradually upgrade it. For the price of an MS you might be able to get the 415 for the same or less, i think someone said they are on sale due to the 416 coming out.
