So many of these upgrades are great but it just depends how much you want to spend. a lot of people go with the 1100lb bags in the rear locker, i went with the 750s because 1100 just seems too big for those lockers but they seem to work for a lot of people. Definitely make a suck gate. For less than $50 you get a great upgrade, and they are easy to make. An IBS in the bow is also a helpful. I upgraded to the 1433 prop and it is nice, but you certainly don't have to have it. I also did the pump upgrade you have a link to and it is great but again, not a must have. I've don't a lot of these upgrades little by little.
