I've been advised I need some #24 baetis for a special trip this summer. I was also advised that I should BUY them. i saw hogwash! There's no reason I can't tie them...

However, I'm having a hard time knowing what to buy for hackle, insofar as size goes... for example, pre-sized hackle like Whiting's 100s only go to size 20.

If i get a high quality cape, grade 1/A/gold, will it have appropriately sized hackle for tying these tiny flies? I'd hate to spend that kind of money and not get what I need, not that I wouldn't eventually use it... while we're at it, what about color also? Would Denny's silver badger be appropriate?

Thanks for any advice
