I use a short shank hook in a size 6. size 8 and smaller are usually slightly lighter gauge and could open up on fish, size 6 is still a pretty small hook when using shorter hooks. I also rather have that wider gape the 2499SP-BL has.
today however I bought Mustad C68SZ size 6. these again are a short shank hook, built for saltwater so they are strong. the gape on them isn't as wide as the Tiemco 2499SP-BL but they are $4 cheaper per package of 25 which is why I'm going to try them out. I have fished the Mustad saltwater hooks for salmon the last few years and I have not yet had one straight out on me unless I get snagged on bottom and the tippet will normally break first
3XL are fairly long hook, I like the shortest hooks possible for salmon flies. salmon (especially coho) have a tendency to work the hook loose and longer shank hooks actually help them in the leverage area to work it free. I do not like offset hooks for stripped flies, I always wonder if they could possibly spin during the strip because of the offset
