M_Boats: reefing lines

I am going to mount some small blocks on my 17 boom to pull down reefs in a hurry. On my larger boat, I ran a line from the becket on the block, under the boom, through the reef cringle, down to the sheave on the block, and forward to a cleat. I am wondering if this will work on my tiny boom as well, or if I should anchor the line on an eyestrap opposite the block. Anyone? Thanks, Tom Jenkins
