Longbow draw weight?

I’m thinking of getting a longbow bout mainly shoot recurve with a draw weight of 40lb on the hand. I’ve also got a long draw length of 30.5”. How do I get around most of those being for sale having a maximum draw of 28 or 29 and big warnings not to pull any further? I’m shooting well with recurve up to 100yards and would be target shooting only but still want to reach that distance with a longbow. Should the longbow be the same draw weight as my recurve. I don’t want to get something that...
