The Polaris Boost is a pretty amazing sled, and if I had the money to burn, I'd probably have ordered one. If I were in a position to upgrade, I'd have a hard time deciding unless keeping the current sled was practical. There will always be a few lemons (was just talking with a guy who picked up a holdover '20 Summit last year that had to go back to the dealer several times), but it does seem Polaris has a weaker batting average on 1.0 products (see 850 motor, series 8 track). Not that I expect the Matryx Boost to be a time bomb, but the potential for lost riding time has to be a consideration. That said, most Poos are pretty good sleds out of the box these days – not nearly as many time bombs as there used to be – and I'd love to get some time on a Slash Boost next season. If the '22s hold up well, a '23 might end up on my shopping list. Although by then, the Rev5 might be a reality... Not going to worry about that for now though!
