Make the difference in success of catching fish? For example if I use whatever hook to tie a wooly bugger. Does it have to be a specific hook?

Any of you buy just a couple different hook to tie all your flies and have the same success rate? Or do all of you tie the fly on the specific hook the pattern calls for?

Was curious about this since I just grab whatever hook I want and tie. Could make sense why lately I've had crappy luck with the fishies.....

Thanks,
Shane
