OK Trident 13 seat upgrade

I have been browsing the forum and reading but still have some questions regarding the seat in the OK T13.
Lets start with this I'm 6'0" 155 lbs soaking wet (as you can imagine not much natural cushioning). The stock OK seat is very thin and uncomfortable so I decided to get a skwoosh anglers butt pad. Still with this my butt still hurts. So now I went ahead and ordered a S2S GTS expedition. I was curious on if it will even fit (width wise) on the OK T13. and if anyone has had any experiences with this seat.

Any and all comments will be much appreciated. 

Shouldn't be a problem with fit with that model. I have the GTS Elite now in my Trident 13 and love it! It fits perfectly. Before that I had extra layer of closed cell foam padding under the factory seat.

By the way... check out the Manta Ray from YakGear.com. if you want to save some $$$ for the same kind of seat. I was going to buy this, but Santa got me the GTS.
Also don't forget they offer a 15% NWKA discount! (see discount codes in classified section)

If it's just the padding you are looking for consider one of those red rubber donuts from the drug store. I am very happy with that solution.

You might look at the OK Big Catch seat. It has been on the market from OK/NZ (RIP) but
you should be able to get one from OK. I have found it to be the most comfortable of the OK
seats, very well padded.

all this talk about upgrading kayak seats, thought i'd post this here before shopping online:

anyone got a seat for sale? the ms. just picked up an older model tarpon 120 w/out a seat, so we're in the market.
