back to diamond, advice?

[gangmobb]

ok so i left my diamond back when ROMS were really kicking it on it, around the time 6.5 was being introduced and i stuck with intx rom 1.6 and i just got my diamond back and im stuck on it for about a week.(until me corporate discount and $29.99 hero arrive) i tried intx's final ROm and it was super SLOW. no offence. i am currently on gadgetfreaks rom as off yesterday and it somewhat solid. nice look, quick for first 5 hours. now its slow again. COULD anyone please RECOMMEND a nice stable rom for me i dont know much about 6.5 or anything newer than that would like to stick to 6.1 but if you can convince me i can probably switch to anything new.. keep in mind i would like it to be fast and im a heavy texter (500+ per day) and heavy data user.. =D will apreciate any help and thanks will be rewarded.. thank diamond users!
