I think raising pre-flop is a mistake.

I think I like your flop raise given that if you make your hand there is no possible low. Also, I would think that you have somewhere in the neighborhood of a 14 out straight draw (16 out straight draw but I think he has two aces in his hand) plus a pair which could become trips against an opponent who most likely has aces with a backdoor low draw (exactly what he had). This is the hand that I would put my opponent on in this spot and I would raise the flop just like you did because I would feel as if I had some folding equity (although, maybe not that much) and that my draw was big enough that it might be +EV just on that basis.

Now, here is what two dimes says:
pokenum -o8 as ad 8d 2s - ah qc jc td -- kh js 6c
Omaha Hi/Low 8-or-better: 820 enumerated boards containing Js 6c Kh
cards scoop HIwin HIlos HItie LOwin LOlos LOtie EV
As 2s Ad 8d 389 389 431 0 208 0 0 0.493
Qc Jc Td Ah 401 431 389 0 0 0 0 0.507

So, you are about even money on this flop - you have an overlay from the pre-flop betting - and you have some minute folding equity so I like your push even more now.
