Hi All;

I've been looking into YLI silk for that past few days, it's available on ebay about $5.00 per 200 meter spool versus $3.50 per 30 meter spool of Pearsalls. The Yli spools fit a standard bobbin whereas Pearsalls smaller spools require midge bobbins.

Check out these flies tied with YLI silk:

Looks to be very similar to Pearsalls.
