I am looking at ZTR with a stamped metal deck (Snapper ZT18H), but the dealer also showed me the Snapper Fastrack XL with a fab deck. From what I can tell the only downside to a stamped deck is the potential it might bend over time, is this true? The stamped deck is 10 or 12 ga so it is not too flimsy. All thoughts are welcome. Thank you.
