Ok so as of right now i have it narrowed down to the 48 scag hydro wb with the fixed velocity deck and the 17 kai, and the exmark viking 48 advantage 16 kawi with the ecs. i found that my scag dealer (RI Grinding for the guys around here) is very nice and helpful and seems to be the model dealer ive been looking for. on the other hand i know the owner of the exmark dealer very well and the pricing would probably be very competitive. basically, im liking the scag a little more BUTTTT the exmark has the ECS. IS the ECS worth buying the exmark over the scag? the scag has the flagship velocity deck wheras the exmark has the trivantage. thoughts?
