A good place to start for trying out ROMs is here
It helped me out
I am new to posting on XDA so at risk of being shot down in flames but I will tentatively put it out there that I used Oxygen for quite a while and am now on Cyanogenmod – just thought I’d mention these because stability is important to me and although I may not be living on the edge with the most exciting new nightly builds of ICS ROMS (probably because I have my ICS fix with my tablet) my phone is stable and speedy.
I don’t expect many people to take any notice of a "newbie" but for what it’s worth my experience has been good with both those I mentioned – then again, as eddiehk6 said, they may be disastrous for you – you just need to try some out, but perhaps these will be a good starting point?
Edit: NB there aren't Sense based but you only said "possibly" with Sense
