Awesome review! Sounds like the ASV is solid but overall doesn't quite stack up to sticks like the ft5 in overall performance. I know you've referenced the TMP Pro - will there be a full review for that stick coming?
The kick point is massively different between the two, you really have to focus on technique and how you load the stick with the AS-V Pro especially compared to the Jetspeeds. I have a hard time recommending the Tacks to people unless they have been using mostly mid or high kicks before.
Last time I checked he was using an AS4 Pro wrapped stick but it is hard to tell what it actually is without seeing the sticker that comes on it from the factory.
Different sticks, Jetspeed would be closer to the Sync. I would take FT6 Pro over both of those. I prefer the Sync's puck feel more to the AS-V though.
