well I feel you there man, I'm 6'4 and around the low 180's to low 190's you seem to be a bit bigger than me but I definetly know the importance of a comfortable running shoe, thing is though...i tend to overpronate and so i need a stability shoe and while it does help decrease injury i really do need some more cushioning on my shoe as well

i have never owned a pair of Asics, to be honest but I do have 2 pairs of shoes of other brands, they are not all that expensive but have worked wonders for me

1.) I have my most mileage on this shoe, the Brook's Adrenaline GTS 8

this shoe has got GREAT stability, it does appear a bit bulky but at the same time it's got a great amount of cushion
they cost around 80 bucks for me they're are new models but i still enjoy these

next 2.) the Mizuno wave elixirs also provide cushion as well as great stability, they are also less bulkier than the Adrenalines

If you want a well cushioned Asics shoe you're going to have to bust the bank a little and go with their higher-end products. I've run in the Kinseis and the Kayanos and put lots of mileage on them and they held up fine. Either of those would get the job done and I would say that they're Asics most comfortable shoes. Good luck.
