I'm looking to get a fishing kayak that I can stand in is the ascend FS10T good for this?

Welcome aboard, Brady!

Ascend makes "descent" yaks, but one complaint on
their site is that it is not very stable. If that doesn't matter,
or you don't plan to stand, it is a great starter kayak.

I say starter because there are better kayaks, lighter, and
much more stable.

i'd really start to check craigslist frequently at this time of year.  it's when a lot of people decide to offload their stuff once it cools down and some great deals can be found and maybe not as many people to compete with in terms of buying it since it's not "in season" for most.

 

I used to be on Staff with BPS, and the D10T is MUCH better than the FS10 for standing, and is much more stable.

I have an FS10 and would NOT recommend standing in it unless you are both light and have extremely good balance. I stand in mine....but I have outriggers for it. I cannot speak to the FS10T as I have never used one but it is 2" wider and about 10lbs heavier. I would tend to think those help it's stability, but it is also a sit on top and you're center of gravity is going to be higher which would hurt it's stability. Reading the reviews on Bass Pro's site people are saying it is very unstable, so it seems to me they made it too bouyant or messed up the hull design. 

TBH if you really want a stand-up ready, with no modification, fishing kayak for that price range I would look at the used market. In the Ascend lineup, the first kayak that I would say might fit your bill would be the FS12T. It's 100 bucks over your budget but you might be able to get it for 500 or 550 when Bass Pro does a sale.  

PSSSSHAW!!! Standing is overrated anyway. The only time I need to stand is spring, when fish are bedding. Then I go with my bud and fish from the back of his Tracker. Then I go back to the same spots with the kayak. I've fished the same spots enough years now that I know where to go without needing to stand. You do gain an advantage from the fish not seeing you standing 7' over them, but lose the ability to see exactly where they are, but you can still see the beds. As you may have guessed, I have one you can't or shouldn't stand in. I'll get an SUP one of these days when I quit buying rifles and have my hot rod already built.
