Anyone throw a tdz spool in their T3 mx? Any increase in performance over the stock spool? Thanks. 

Haven't tried the tdz spool, but if you want a real boost in performance, the rcs1016 spool is outstanding in the T3 MX.

The stock tdz 103 spool with gold inductor is just an average spool. The tdz R+ spool is something special though. Prettt easy to control and is great for distance. You can order the inductor assembly from Japan but after shipping will probably be around $45 total. Still a good price since you got the spool for free and the R+ spools sell for about $60 these days. RCS 1016 is good too. Don’t come up for sale as often as they used to but going rate is about $50 when they do. 

I’ve done the Z 103 Gigas spool in my T3 1016 and felt it wasn’t an upgrade at all. I think the stock spools in the T3’s are pretty good. I actually put the MX spool in an SS SV  and it was a big improvement over the SS SV spool.
