I'm not sure why a brand like Salix, that does not rely on TV exposure, bothers to change so much?
Historically they don’t change much. The pod has been flagship bat since year dot, SLX been around 6/7 seasons, the Raw & RawT20 more recent inline with shorter blade option plus one other model that can change but normally stays in the range for a few seasons. Even stickers tend to only change every 2 or so years as do the softs.
Tammy Beaumont is the only pro who uses a branded Salix and she uses the most Minimal of the range in the Raw.
Have to wait and see what 2018 brings
