Jeeper,
I would go with the 32 inch wide bite, same HP as the 38 or 36 inch bite.
The smaller bite means you have more HP per inch of bite, greater throw distance!!
That would also save you about $400.00!!
You never mentioned the Honda blowers.
At the price of blowers you are looking at, I would go with the Honda 1132 tracked blower.
You would then have the Rolls Royce of blowers. IMHO
You can buy the Honda for about the same price as the 36 and 38 inch bite machines you are considering.!!!
