Both are great sleds!
Poo have much better throttle respons than E-TEC, Period!
In the really steep Poo handles better!
Very few, I will say no one with a -14 Poo have QD problems!
Very few have succeeded to bend the tunnel, I don't now anyone hos has!
Carbon fiber tubs! No problem att all and we have "really" done our best!
The only thing I don't like with the Doo is the throttle respons, it really sucks.
I wasn't sure if I should take Doo T3 or TDS 163, I went with the Poo TDS 163.
Haven't had one singel problem with my Poo Pro 155 -13 or -14.
