well if you are looking for uniform numbers, you may have started a "jihad" lol..........its really up to you, the rosters that are out there for download are "meant" for solo leagues and can be adjusted to the way you want....
I have a roster set on my site...
www.simleaguecentral.com
you will need to register for the site and then you can get to the downloads
and CBL's rosters are really good as well and because i dont remember the link off the top of my head, hopefully someone will chime in with where you can get his (sorry about the brain fart CBL)
its really up to you...............mu roster set is available for both OOTP 5 and 6 and so is CBL's....i havent heard and drastic complaining other than "can you tweak this, adjust that turn that and touch this" *why do i feel like im calling a sex line?* but feel free to try mine out and CBL's as well.....there are other sets ( a ton, that have been done and hard work went into them) but i cant remember.....CBL's roster set is probably the most popular, but its a matter of opinion on what is "the best"......hopefully that will help you out
