I am running stock 6.5 and haven't seen any major problems I wasn't able to find a tweak for. Speed wise it's OK.

Also, I ran SPB Mobile Shell for a few months, first loved it to death, then after a while it started getting really annoying.. plus, even though it left more free RAM than the Sense, it was also laggier.

So, I disabled WM6.5 Start menu altogether (that alone cleaned up some 15 MB of RAM), replaced it with QuickMenu, reverted back to Sense but installed CHT2.0 on top of it, and it's been running like a champ ever since.

Not to say custom ROMs aren't a great thing, but I had no need to flash - and I am no noob when it comes to reflashing my device.

Good luck with TP2, as long as the hardware doesn't crap out, it's a very capable phone.
