Just ordered my DT1350s, really looking forward to them.

Why debate on whether to get T1 or HD800.. or others?
It's not hard to get one for a good condition off the classifieds here. If you don't like it, you can sell it and not really lose much (if any).
But, like I said earlier...from personal experience, the T1s with serial #s after around # 4000 have less spikey treble. I have tried both. The new one is not fatiguing at all, and the sound is just excellent, very very balanced.
Please make sure you use the T1s with a good amp and reasonably good source. If they sound bad, I'd say it's most likely that they are picking up noise in the equipment chain, among other things. I am using mine with an Audiolab 8200CDQ DAC -> Eddie Current ZDT. Excellent pairing, quite happy with it.
Yes, there is a huge difference. The older serial numbers up to # 3950 had harsher (and generally harsh..busy treble).

You can see the spike in the freq. response at 8000 - 9000 Hz is now corrected and made much flatter. This is what...
