In terms of testing, or spring modification? I'm not sure when they will get their 2017 race bikes in, but I'm sure that Dalton and the rest of the team, including Ty will be putting them through their paces.
I just find it odd that the OEM special parts already has a spring kit for the AER 48 forks for those that choose to use springs.... They write that their are advantages and disadvantages to both set ups. WHat I do love about the TX300 spec is that you have options, when I get my TX300(if is better) I will for sure ride the crap out of the AER forks before even considering a full fledged mod like springs, personal set up takes time and effort. I just wished that the OEM also presented their chassis balance pressures for the AER forks to go along with their rear spring rate chart, at least to get some idea of what pressure matches with what rear spring. Maybe the clue is in the 3 PSI step comment----for every rear spring step go up 3PSI in the forks???
