I dont know if this will be read but here goes anyway
my brother has a avalanche, I have a 901 they are both in my opinion great boats, when Im on his deck it basically feels like im on mine. my boat is faster due to the fact he is running a 115 4 stroke, I run a 200 efi. his boat runs araound 48-49 depending on the wind but he does plane out alittle faster than I do. the only thing he wishes is he would of went with the 150 and I agree. I love my 901 and he loves his ave, I like glass he likes his glass want a be but it does handle ruffer water almost as good as the 901 but we fish smaller lakes and the ohio river most of the time. If you fish large bodies of water I would probably go with the 901 due to the fact the ride is a little drier and the cost will almost be the same with the 175 on the ave to the 200 on the 901, plus you get more features on the 901.
But if you like to get really shallow go with the ave it does not draft as much water, which will help ya when on the trolling motor, the only thing I have missed from my old hydrosport. a couple of inches does make a difference when the water is low I have found.
