Coil all the way. My first 5 Spot came with a DHX Air shock and it felt totally dead, really not impressed at all. Had it serviced and checked over and it was still just as bad. I then bought a DHX coil with a ti spring and it was fantastic!
When I bought my second Spot many years later it came with a Pushed RP3 and as good as it was it still didn’t feel as plush or as controlled as the coil shock. Forget the weight penalty, it’s how it rides and you will enjoy it far far more.
