A buddy rented one for Deso Grays in June from Mesa State in Grand Junction. Held a 16o yeti just fine, held my 150 qt igloo just fine and a big dry box. Was fun to row, and could have swallowed a ton more gear.
I just ordered a 16xt which supposedly has 7'9" straight tubes, the pro is supposed to have 7'7" straight tubes.
The xt is also wider by 10 inches total, some of that being taken by the 22" vs 21" tubes.
I'm in the buy once cry once camp on this boat. Loved my Achilles and NRS and they're both now in happy homes, one in AK and one in Southern CO.
Good luck, they're both great boats
