Looks good but I don't believe it will do 190 or even close to that but it may do 180 but more likely mid to high 170's. You need excellent wood to do 190, a character stave just won't cut it.
Many of the highly reflexed recurves I was making years ago wouldn't do 190, most would do mid 180's. Looking though my old photos I've been able to find 3 that hit 190
