taking my top off...one or two straps?

ok, so here is the plan
im going to put in an eyebolt towards the back of the truck and run a cable down
hit a tackle block and back up (leaving the eye on the block open)
up into a second tackle block, mounted a few inches past the eyebolt
the run the cable forward to the front of the truck, into block #3 and down
hit block #4 at the front of the top/back of the cab and back up, into block #5

ill run two cables like this, one on the driver side, one on the passenger side and most likely tie them together after block #5 and into a hand crank like @1973Barracuda mentioned

then i will get in, pop the top up an put a piece of 2X4 in between the roll cage and the top, towards the front of the truck
then i can run a line connecting the eyes of block #2 and #4 (or perhaps even cross them, from left to right?)

this should allow me to lift even and effortlessly , sound good?
