I've got about 16 hours on my new 2415 HST. Love it! I was leary of the HST, having only driven between the knee shifting gears before, but it works well.
The dealer didn't have a 24 in HST on the lot, so I only got to drive the 28 and 32 in the HST. those were LOUD (squealing/whiningthe HST, that is).....the 2415's HST is much better. Nice and quiet. Squeals a bit in reverse, and do wish reverse was faster....
