Congrats on your new vise and welcome to fly tying. Your crappie and blue gill jig hooks should be fine, and the vise should hold other hooks just fine as well.
The only caveats I could think of off hand would be not to use ‘bait holder “type hooks with the barbs along the shank because they’ll cut your tying thread, and to probably stay away from hooks that have a radical offset often labeled “reverse bend” where the point of the hook is bent to one side of the shank because the fly may not track straight in the water. If you have hooks like that and they cause a tracking problem you can try bending them back in line with pliers.
As for fly tying hooks, they’ll often differ depending on what you’re tying.
Here aere some of the common types of fly hooks:
Dry flies often tied on standard shank with light wire (to aid in flotation)
Nymphs- straight shank, standard or heavy wire, usually 1, 2 or 3 extra long, often “perfect bend” to accept beads
Wets standard shank heavy wire
Streamer- often 3-6 extra long shank
And as far as inexpensive hooks, in addition to Hook and Hackle a lot of folks have been recommending the hooks from Allen Fly Fishing Allen Fly Fishing
Materials – including hooks, can be pretty confusing so if you have any questions just tell us what you’d like to tie and feel free to shout—folks here will be happy to help you sort through all the choices of stuff.
