Red line, Laguna Seca Pro, and Avro... so end up I picked the Avro. BTW, big thanks to D-Store in San Francisco helping me to pick a right one. Avro is the most comfortable one. It fit better than Laguna Seca Pro, and much much better than Red line - really can't used to the "bib design". So far I like it a lot; but it's not prefect - sleeves are about .5" too long for me. For your reference, it's size 38/48, and I am 5'-8" and weighted 153lb (lost about 10lb since last suit - down sized from 40/50!!!). It has enough room for under suit and full size Dainese back protector.
Can't wait for a ride tomorrow with my new suit!
